[@7inrain]

I can so much relate to Neil Shubin and Tiktaalik. Not the least because I'm living near a paleontological site that made history as well, the Neander valley (in German: Neandertal) where the first Neanderthals were found. What is still more amazing and barely anyone knows (apart from some local geologists): The limerocks in the Neander valley formed during the time when Tiktaalik lived, around 380 million years ago in the Middle Devonian. So the coral fossils that I have in my book shelf are exactly of that age. Everytime I have them in my hands I think of Neil Shubin and Tiktaalik.

[@jaschabull2365]

[@colin2709]

I am so glad to be living in a time when we have a handle on the development of species; we can make sense of present day diversity and trace back that development to its origins. It was 40 years ago when I first read Darwin's origin of species (on a Philosophy course, lol). It took time and the help of others to synthesize its contents and develop my understanding. I am enormously grateful for the work of scientists (Darwin himself and those that followed up his work). I am not sure I have the patience for such work, but I do love the results. I feel that that people such as these have rescued us from the magical 'explanations' with which were stuck with for so long.

[@talismanskulls2857]

If they want to know why or what motivated the Tiktaalik behaviors, cross compare that to a Snakehead fish or any number of such fish that can and do crawl out of the water, use their fins like feet, care for their young and what causes them to go on land in the first place. Mysteries over and its simple. Its also not the only"fish with those features. Take how everyone was making claims about coelacanth fish as the ancestor of all land animals. Everyone claimed they were extinct millions of years ago and now we see there are two species of them that still exist and they do not walk on land. Look at whales that are said not to have started in the water but on land and that is only claimed because whales still exist. The reality is things have been moving to and from the land and water since life began. worms were among the first species and they were and are found in all bodies of water, a rare species in ice called ice worms and in the soil. We have insects in water and on land as well that are said to have evolved from worms and another line evolved into fish, etc. They ignore the fact that kind of evolution in the water was occurring on the land as well and the have no clear evidence because worms don't fossilize well due to soft tissues Yet they dont acknowledge land insects could have evolved on the land from land based worms? And worms evolved from what, and those evolved from what? Germs. And germs are found everywhere as well even in deep rock, still alive and doing all their little microbial stuff. SO tracing all life to one source is trying to force a linear structure into a "tree" and ignoring its many roots, but also ignoring the fact life does not fork out and follow a tree pattern. Its chaotic, and is more like a tangled web with no single point and having many innumerable cross points back and forth at different times for all sorts of diverse and known as well as unknown reasons. Even if we look just at the related human ancestors and cousin species, there have been many changes, cross sectioning, extinctions, and so forth of so called evolution and devolution.

[@rolo5424]

How do you explain the Cambrian period then when many groups of animals suddenly appeared full formed out of nowhere? There was no transitioning from anything that had gone before. So it is not true to say that evolution accounts for how animals evolved in small incremental changes and steps since there are no transitional fossils before various groups of animals appeared already fully formed.

[@dancingnature]

The Cambrian animals evolved from Precambrian animals . What you see during the Cambrian is the evolution of hard body parts

[@corporateturtle6005]

@@jimwills2094 Speaking of "propaganda" how's that book of fables you worship, the bible?

[@willw5868]

really simple actually Ro. Precambrian fossils do exist, they are just MUCH rarer because mineralized tissue (the part of animals that fossilizes well) did not really exist in the animals of that period. The Cambrian explosion is not animals "appearing", it is just them evolving from animals which did not fossilize well and thus are very rare in the fossil record. Hence the lack of transitional forms.

[@jpr2177]

I still strongly believe the natures target animal was a bird not the four legged creature. The animal design of heart & lungs coordination with rib cage expansion and pulling in air with every stroke during all stages of flight does not match to any other movement so perfectly plus the the control of flight through end of wing digits and perching on branches n hunting animals and bringing to mouth to bite is not as perfect elsewhere as in bird life. We gets feet spasm by trying to grab something in fear or pleasure also resemble birds. I think we’re wrongly trying to prove the evolution backward or by matching the pictures we found instead of looking at the bigger picture of reading the mind of the creator. “It” might have wanted the bird and not the fish, frog or monkey! Think about it! Mhmd!

Frogger 81 Carbon dating is unreliable for things that are old. Radiometric dating is the big umbrella, and that disproves it if you use certain elements. Radiometric dating isn't the only thing you can use, though. I have a question: If all of the animals were created at the same time/day, then why do we find that the layers of the earth separate the fossils between time?

[@robrosen7291]

Satan is a lie created by uneducated, superstitious Pagans with an agenda. First, they scare you, and keep you in fear. Then they offer you a safety net and protection. If you follow their rules, and tithe faithfully, they'll keep that bad ol' Devil away. If you give them more, you're even holier and get better protection. It's all about money. Your money to them to keep the fear at a low level. If you stray and don't give them enough money, well then Lucifer starts nipping at your toes again.

[@evanwademan5602]

Why would would god or satan put so much effort into creating this “lie” when most people will never notice? Also we can apply our knowledge of evolutionary biology to other fields, such as creating new medicine & determining how closely related particular species are. But you can’t do that with creationism, its always “evolution is just a theory” & about proving an entire field of science false

Basically, it comes down to a pattern. From the start, for those that believe the creation of the universe came about by natural means have set their pattern. Their pattern to believe in the impossible. They set their pattern for no matter how illogical and unscientific it is, they'll still accept it. We all do stupid things. Hopefully, we admit them and learn from them. It's not a matter of who's smarter; it's a matter of who loves truth more. For those that don't love truth, you can find reasons to believe anything; you'll find excuses for what you want to believe. For others though, like myself, I don't care what I want to believe. I care about what I should believe and why. It's easier said than done, but in the end well worth it. I just don't want to remain stupid.
