Tetrapod Evolution 5of5

Tetrapods are vertebrate animals having four feet, legs or leglike appendages. Amphibians, reptiles, dinosaurs/birds, and mammals are all tetrapods, and even the limbless snakes and whales are tetrapods by descent. The earliest tetrapods radiated from the Sarcopterygii, or lobe-finned fish, into air-breathing amphibians. The first tetrapods are now thought to have evolved in shallow and swampy freshwater habitats, towards the end of the Devonian, a little more than 365 million years ago.

This documentary walks through our early understanding and discoveries regarding the evolution of tetrapods. The list of known fossils possessing transitional features continues to grow.

Osteolepis, Eusthenopteron, Sterropterygion, Panderichthys, Elpistostega, Tiktaalik, Elginerpeton, Densignathus, Ventastega, Metaxygnathus, Obruchevichthys, Hynerpeton, Acanthostega, Ichthyostega, Whatcheeria, Tulerpeton, Pederpes, Greerepton, Crassigyrinus, Pholidogaster, Pteroplax, Baphetes, Balnerpeton, Dendrepton, Silvanerpeton, Proteogryinus, Eoherpeton

LOL!

Institute Of creation research.

Such fail!

[h4tchetman]

sometimes i want to round up all the religious an have them go to school lol but i know that they would all kill themselfs.. we would need to give them councilling while they attend school to help them deal with the pain of being lied to for so long

[rahoolbhimani]

almost done #focused

[FellOnSoundGarden]

Institution of creation research .....lmao... what type of research do they conduct there? Doesn't the simple fact that we have fossils of very different dates spanning billions of years immediately prove creation wrong? Aren't all species supposed to be made on the same day? I would love to see what type of "research" is done there.

Marvellous documentry.What a beauitful,humbling truth that evolution is!! How much more gratifying it is,to think that we descended from such simpler forms and to comprehend the wonder of where evolution will take life on Earth in the future after we as a species are long gone.So much more edifying than the stupidity of a bronze-age narrative about a talking snake,an apple and a vengeful god lol.

[KadoatieXD]

I knew dere were not gunna mention Tiktaalik from the very start! ALTHO... I very much expected Tiktaalik 2 be mentioned in the very last part! Tiktaalik was in my mind the whole episode!!!!

The bible teaches you to turn the other cheek, to love your neighbor, not to kill or lie, ,,,,, but those are not important.................The universe being created in 6 days is important. After all, the bible was a science textbook, right?

[TechnicallyTechnical]

What about Tiktaalik?

@Pazma1 Random mutations only a small part of total evolutionary process. They account for changes in DNA structure which translates into changes in protein synthesis. New proteins react differently (yet predictably) in their chemical environment then their predecessor, sometomes manifesting as a new phenotypic trait. Typically, yes, the 'bad' ones are rooted out, and the good ones proliferate. This is not always the case however.

@Shepherd1OFH

I'm just a layman, so maybe you know more about this than I do. But I thought that random mutations happen and the stuff that's beneficial to survival sticks around, the stuff that isn't dies out. It's random Jim, just not as we know it. lol

[Shepherd1OFH]

@Pazma1 Except 'chance and accidentds aren't the basic notions. Physics and chemisltry are. Evolution obeys the the same universal laws and principals. It's direct cause and effect mechanics, not 'chance and accidents'.

@Shepherd1OFH

I'd rather they tell the truth as it is than pander to people who can't even grasp the basic notions of how we all came to be.
