Cambrian extinction & explosion didn't happen just because some few stray animals survived? So apparently according to this video's logic, dinosaurs never went extinct just because some few lizards and crocs are still alive today? And then he puts forward how "rare" and "puzzling" the fossil records are to support that theory. Such argument can be easily reversed to disprove those "treasure trove of fossils" that claim to bust the Cambrian explosion myth, don't you agree? That they are a rarity and thus an exception to the rule, instead of the "rule" itself?

How can you tell the difference between a species going extinct or evolving into a more modern type?

[@MALICEM12]

Wildgraywolf1 simple, evolution doesn't just "happen" in fact it technically never stops, things are always changing and evolution takes time, however if something were to disappear in the span of.... say a hundred years, than that is extinction, because no animal can evolve into another entire species in a single century. Humans today are the same as the were in the days of ancient Egypt, and that was thousands of years ago, if something stops in only a fraction of that then it wasn't merely "they evolved into something else".

[@bilalamarumosi8282]

Wildgraywolf1 can you name an instance of that happening?

Wildgraywolf1 Also Richard lenskis experiments have shown speciation and novel traits evolution in ecoli, polyploidy is the instant speciation of plants by accidental doubling of chromosomes.

What if the majority of animals we think went extinct acually evolved? Scientists always talk about distinctive time periods like Jurassic, Triassic, etc. But they never talk about the transitional periods between them. All they say is "this animal lived during this time" then they skip to a whole different time period and don't explain what happened to the animals from previous time periods. How did dinosaurs even evolve? They didn't just appear out of nowhere. What came before the dinosaurs? Were the dinosaurs even the first life form on earth? Where did mammals come from if there were only reptiles and other life forms except mammals? There's too many unexplained questions, and all science can come up with is "this appeared during this time period". What the hell happened before that?! That's like being a witness to a crime scene and only being able to tell reporters "WHEN" the crime happened. What happened before that? What happened after that? Why did it happen? Who was involved? How did we get from this point, to this point?! These are basic questions!

If you are looking for a primary source to answer some basic questions like length, width, features, etc.; A really great resource is the Burgess Shale website, which is part of the Royal Ontario Museum, at burgess-shale.rom.on.ca. It has tons of fossil photographs along with some basic descriptions. For example, the Pikaia photo used for this video was based on a fossil that was 53 mm long or about 2 inches, which is really amazing if you think about it. So small and yet it had the beginnings of a complex central nervous system.

Watching these videos, doing my research the dramatic rise and drop in the oxygen levels. Also land mass and placement is really the cause of all these extinction and new developments. I'm really enjoying all of this knowledge.

[@Alexaflohr]

I'm missing something here. How do we know that there were more lifeforms than those that we have found in the fossil record? Isn't the fossil record basically the only evidence we have of such ancient organisms? Is there some prediction that you can do by tracking mitochondrial DNA or something, or is this purely just speculation based on the inductive evidence we see in our era?

[@dgodfrey9189]

Both. There are lots of soft-bodied animals around today that simply don't fossilise under normal conditions. For example, the fossil record of nematode worms is pretty much non-existent (last I checked there were two fossils), but today there are over 20,000 known species, and they're found pretty much everywhere. So they must have been around at the time as they're a clearly distinct taxonomic group and of the things they're most closely related to, arthropods have a very good fossil record. So they've been around at least as long as them. But we only have a couple of fossils to show for it.

[@damonhicks969]

Why does he say at 0:40 disappeared from the fossil record when it is known that the fossil record is not a complete list of every creature that ever lived, just the ones that happened to expire in conditions that favor fossilization. A creature can be in an area primed for fossilization where the fossils are easily found by man. Then climate changes and sends those creatures to an area where the corpses are devoured before fossils can be created or they are still on the ocean floor creeping towards a coast at 1 cm per year with a thousand miles to go. That is why the so called "fossil record" will constantly have to be corrected as new evidence is found. So the fossils didn't disappear from the record they just aren't where your looking for them. The same goes for life in the universe, just because you don't see it now just means it's not where your looking for it.

[@StarWarsomania]

Damon Hicks ...because it did disappear from the fossil record. The "fossil record" is not synonymous with "existence".

[@damonhicks969]

StarWarsomania nope, it didn't disappear from the fossil record. Here is the definition .A term used by paleontologists ( see paleontology ) to refer to the total number of fossils that have been discovered, as well as to the information derived from them. ( See evolution of Earth.) ergo it wasn't "un"discovered and was still slowly evolving the whole time and chances are that any new fossils being created from a recently deceased specimen just won't be discovered for millennia because they live at the bottom of the ocean where paleontologists have difficulty breathing while digging up fossils.
