How Whales Became The Largest Animals Ever

Whales are the largest living animals that have ever existed on this Earth. A blue whale can grow to a whopping 110 feet in length, outweighing even the dinosaurs. But curiously their story begins from rather humble beginnings. Here is the story of how whales became the giants of the sea.

Following is a transcript of the video:
Whales are the largest animals to ever exist on this Earth, outweighing even the dinosaurs. These titans roam the oceans in search of food, but that wasn't always the case. Millions of years ago they used to be land dwellers. Here is how whales ended up becoming the biggest of them all. Following is a transcript of the video.
Whales are the biggest animals of all time. Heavier than elephants, wooly mammoths, and even dinosaurs!
But they weren’t always the titans of the sea. Let’s rewind the clock around 50 million years. No, you won’t find any whales here. You have to go ashore. Meet Pakicetus. The very first whale.
Life on Earth spent millions of years clawing its way out of the oceans. But whales took all that effort and threw it out the window. From 50 to 40 million years ago they traded in their four legs for flippers. In fact, some whales today still have leftover bones of hind legs!
Once submerged, their weight under gravity no longer mattered so they could theoretically grow to enormous proportions. And they did. Today, a blue whale is 10 THOUSAND times more massive than the Pakicetus was.
But this transformation wasn’t as gradual as you might think. In fact, over the next 37 million years or so whales grew increasingly diverse but their size remained small. And were only 18 feet long. Making them easy prey for predators, like giant sharks.
It wasn’t until around 3 million years ago that an ice age tipped the scales in the whales’ favor. Ocean temperatures and currents shifted sparking concentrated swarms of plankton and plankton-seeking krill. It was an all-you-can-eat buffet for the baleen whales, who grew larger as a result. And the larger they became, the farther they could travel in search of more food to grow even more. You can probably see where this is going.
3 million years later, humpbacks, for example, have one of the longest migrations of any mammal on Earth, traveling over 5,000 miles each year. As a result, modern whales are the largest they’ve ever been in history.
Take the biggest of the bunch the blue whale. It weighs more than a Boeing 757. Has a belly button the size of a plate. And its network of blood vessels, if you laid them out in a line, could stretch from Pluto to the sun and back over two and a half times!
In fact, the largest blue whales are so huge that scientists think they may have hit a physical limit. When they open their wide mouths to feed they engulf enough water to fill a large living room. So it can take as long as 10 seconds to close them again.
Scientists estimate once a whale is 110 feet long it can’t close its mouth fast enough before prey escapes. So it’s possible we’re living amongst the largest animal that will ever exist. Lucky for us, they mostly just eat krill.
This was made in large part thanks to Nick Pyenson and the information in his new book, “Spying on Whales.”

It is genuinely awesome to think how far mammals came after the dinosaurs, pterosaurs and sea reptiles went extinct. Giants like Paraceratherium (Indricotheres) and Palaeoloxodon Namadicus could surpass the biggest theropods and even rival some sauropods in size, canines and felines the pack-hunting roles of the dromaeosaurs before them, and mammals living in the ocean - the titanic whales and brilliant dolphins - became larger and smarter predators than the sea reptiles ever were. Even the mosasaurs would be shoo'd off by the giant sperm whales or taken down by pods of orcas. The dinosaurs may still be around in the form of birds - and, make no mistake, birds are damn diverse and numerous - but even the largest of them today can't hold a candle to the modern sea giants. Little, dog-sized Pakicetus, which lived only several million years in the wake of the KT extinction, definitely saw to that.

@@saturn722 They are not assumptions. There are many stepping stones of intermediate fossils that fill in pieces of a much larger puzzle. And what is so great is that if one is so inclined, they can look up all of this research for themselves.

[@saturn722]

@@Lemarcus03 Intermediate Fossils you say?? Is that the same as transitional fossils? You know, fossils that show one species morphing into another? There should be trillions! And they should also be quite obvious. I’m 60 years young and have done a little research while looking for the truth. Science now says there was something called the Cambrian Explosion. Fully formed animals as we know them today that appeared at the same time. At least that’s what the fossil record shows. They think it happened about 550 million years ago. I wasn’t there so I can’t say.

[@Lemarcus03]

@@saturn722 why should there be trillions? Every skeleton does not become a fossil. And species are not morphing. There are incremental changes over generations so all fossils are transitional. If you were to do more than a little research, you can learn how they figured these things out. Because, just as you said, none of us was around. Science is always subject to new data but so, so many successful predictions havw been made of certain intermediate fossils from certain time periods so as to make the Theory of Biological Evolution one of the best documented.

This article is about a marine mammal. For other uses, see Whale (disambiguation). For further information, see Cetacea. Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago. The whales comprise eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales). Whales Whales are not a taxon, they are an informal grouping of the infraorder Cetacea Southern right whale.jpg Southern right whale Information Classification of Cetacea Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Cetartiodactyla Clade: Cetancodontamorpha Suborder: Whippomorpha Infraorder: Cetacea Families considered whales Parvorder Mysticeti Family Balaenidae Family Balaenopteridae Family Eschrichtiidae Family Cetotheriidae Parvorder Odontoceti (excluding dolphins and porpoises) Family Monodontidae Family Physeteridae Family Kogiidae Family Ziphiidae vte Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing − their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey. Whales have evolved from land-living mammals. As such whales must breathe air regularly, although they can remain submerged under water for long periods of time. Some species such as the sperm whale are able to stay submerged for as much as 90 minutes.[1] They have blowholes (modified nostrils) located on top of their heads, through which air is taken in and expelled. They are warm-blooded, and have a layer of fat, or blubber, under the skin. With streamlined fusiform bodies and two limbs that are modified into flippers, whales can travel at up to 20 knots, though they are not as flexible or agile as seals. Whales produce a great variety of vocalizations, notably the extended songs of the humpback whale. Although whales are widespread, most species prefer the colder waters of the Northern and Southern Hemispheres, and migrate to the equator to give birth. Species such as humpbacks and blue whales are capable of travelling thousands of miles without feeding. Males typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for one to two years. Once relentlessly hunted for their products, whales are now protected by international law. The North Atlantic right whales nearly became extinct in the twentieth century, with a population low of 450, and the North Pacific grey whale population is ranked Critically Endangered by the IUCN. Besides whaling, they also face threats from bycatch and marine pollution. The meat, blubber and baleen of whales have traditionally been used by indigenous peoples of the Arctic. Whales have been depicted in various cultures worldwide, notably by the Inuit and the coastal peoples of Vietnam and Ghana, who sometimes hold whale funerals. Whales occasionally feature in literature and film, as in the great white whale of Herman Melville's Moby Dick. Small whales, such as belugas, are sometimes kept in captivity and trained to perform tricks, but breeding success has been poor and the animals often die within a few months of capture. Whale watching has become a form of tourism around the world.

Actually there are 30 extant orders of mammals, Tachyglossa (Echidnas and Fossil Relatives), Platypoda (Platypus and Fossil Relatives), Didelphimorphia (Opossums), Paucituberculata (Shrew Opossums and Fossil Relatives), Microbiotheria (Colocolo and Fossil Relatives), Notoryctemorphia (Marsupial Moles and Fossil Relatives), Dasyuromorphia (Carnivorous Marsupials), Peramelemorphia (Bilby and Bandicoots), Diprotodontia (Diprotodonts), Cingulata (Armadillos and Fossil Relatives), Pilosa (Sloths and Anteaters), Tubulidentata (Aardvark and Fossil Relatives), Macroscelidea (Elephant Shrews and Fossil Relatives), Afrosoricida (Tenrecs, Otter Shrews, and Golden Moles), Hyracoidea (Hyraxes), Proboscidea (Elephants and Fossil Relatives), and Sirenia (Sirenians), Soricomorpha (Shrews, Moles, Desmans, and Solenodons), Chiroptera (Bats), Erinaceomorpha (Hedgehogs, Gymnures, Moonrat, and Fossil Relatives), Pholidota (Pangolins), Carnivora (Carnivorans), Perissodactyla (Odd-Toed Hoofed Mammals), Artiodactyla (Even-Toed Hoofed Mammals), Cetacea (Whales), Lagomorpha (Lagomorphs), Rodentia (Rodents), Scandentia (Treeshrews), Dermoptera (Colugos and Fossil Relatives), and Primata (Primates), these eight orders of placental mammals Soricomorpha, Chiroptera, Erinaceomorpha, Pholidota, Carnivora, Perissodactyla, Artiodactyla, and Cetacea are part of the great superorder Laurasiatheria, therefore Artiodactyla and Cetacea are more often treated as separate orders and the orders Soricomorpha and Erinaceomorpha are not closely related and do not form a monophyletic group.

[@MrGreenalien22]

That’s nice and all, but what specific microbiological changes occurred during all that time to stimulate that rapid growth in whales? I mean both whales and dolphins actually belong in the same clade (cetacea), but you don’t see an evolutionary growth of dolphins over time. Why not? I ask because I love these marine mammals :)

[@MrGreenalien22]

Well, I asked about microbiological changes not necessarily feeding behaviors because I'm sure the feeding behaviors were influenced by something more intricately genetic, but thanks anyway.

[@MrGreenalien22]

I agree, but how do you know what I know or do not know? Humbly speaking, you can't just pass judgment (or imply it) based on what someone else says or addresses. I did do some research though on the evolutionary history of whales and dolphins and found that both odontocetes (cetaceans with sharp teeth) and mysticetes (cetaceans with baleen plates for teeth) diverged from their common ancestor about 35 million years ago. Now, what is interesting is that this recent common ancestor had sharp teeth, meaning that the baleen plate teeth in some whales (like the blue whale) is a derived trait, which is really intersting to me. My question was asking about the microbiological and genetic changes that occurred to develop these traits in whales, traits like baleen plates and enormous size, etc., that are not found in a cetacean like the dolphin. I just wonder what genetic changes could have taken place in the DNA of that common ancestor to produce an animal that once had sharp teeth to one that now has bristle-like teeth. How can these changes just completely "revamp" the teeth composition and growth capacities of whales to make the magnificent blue whales that we see and observe today? Such information is a bit more complex/difficult to come by, but it would definitely make the cetacean evolution line seem more complete. Simply put, all of this has got to be more than just "method of feeding." Thanks for reading! :)

[@MrGreenalien22]

Ok, I read a scientific article discussing how mysticetes transitioned from teeth to baleen over time. The paper provided phylogeny, fossil, and gene analyses of different mysticete species and more info that goes too in depth for me. Anyways, what was most interesting to me was that there were some mysticetes that had both teeth and baleen present at one time in the whale phylogeny. The paper explained how some genes of several whale species exhibited frameshifts and stop codons in the genes AMBN and ENAM, which both code for proteins necessary for tooth mineralization/development. These mutations would gradually lead to the loss of teeth in the whale species line that would explain why mysticete whales of today only have baleen and filter-feed. The proteins would no longer be made, leading to the loss of teeth and the whale species' increased reliance on baleen to obtain food. Why these specific mutations occurred at the time that they did is not really clarified by the paper, but it does provide several hypotheses about the change in whale species' behavior and feeding habits that helped usher these traits down the whale phylogeny. Either way, many researchers disagree over these. So you are right. How baleen was developed in whales to replace teeth is a matter of debate. Either I'll have to do more research or just somethings can't be entirely explained or understood. And all of this is just scratching the surface because it only covers teeth. How whales grew to their enormous sizes, how their oral cavities expanded greatly to accommodate baleen, how skull shape and structures were morphed to be the way they are today, it's all too complex and requires more understanding than I think I can handle. Thanks for sparking this research interest in me, though. :) Any of your thoughts? Article: Deméré, T. A., McGowen, M. R., Berta, A., & Gatesy, J. (2008). Morphological and molecular evidence for a stepwise evolutionary transition from teeth to baleen in mysticete whales. Systematic Biology, 57(1), 15-37.

[@caroselloshow5615]

Greenalien22 well damn you answered yourself lol. But to explain why this mutations occurred you should always look at the changes that occurred in their habitat. If the habitat of the ancestor of whales didn’t have a huge presence of water the animals with the mutations that can give different types of limbs that were adaptable to water would never occurred, and we wouldn’t have whales but different animals. Its always because a change in the environment that can be caused by the slow movement of the tectonics that causes a change in the climate or by many other factors. But surely this animals didn’t change but they were selected becoming better adaptable to their new environment
