Fossils for a creature that looked part fish and part limbed animal were recently found in northern Canada, a paper in the latest issue of Proceedings of the National Academy of Sciences reports.
The beastie, Tiktaalik roseae, represents the best-known transitional species between fish and land-dwelling animals, according to researchers. It lived 375 million years ago.
“Tiktaalik was a combination of primitive and advanced features,” co-author Edward Daeschler, Associate Curator of Vertebrate Zoology at the Academy of Natural Sciences of Drexel University, said in a press release.

While classified as a fish, Tiktaalik looked like a cross between a fish and a crocodile. It could grow to 9 feet in length, and likely spent its days hunting in shallow freshwater environments. It had gills, scales and fins, but also had features associated with terrestrial animals. These included a mobile neck, a robust ribcage and primitive lungs.
Of most interest to the researchers, its large forefins had shoulders, elbows and partial wrists, which allowed it to support itself on ground.
The presence of these limb-like features challenges the theory that such mobile hind appendages developed only after species transitioned to life on land.
“Previous theories, based on the best available data, propose that a shift occurred from ‘front-wheel drive’ locomotion in fish to more of a ‘four-wheel drive’ in tetrapods (four-footed animals),” said co-author Neil Shubin, who is a professor of Anatomy at the University of Chicago. “But it looks like this shift actually began to happen in fish, not in limbed animals.”

Even some modern fish can walk, such as the African lungfish. You can see a bit of that, and learn more about this unusual fish, in this video.
Lungfish often look like they are slithering, more than walking, but if you see them in an aquarium, their little limbs are evident, and they do walk around.
It’s likely that Tiktaalik did the same, with its later relatives walking completely out of water and onto land, where they eventually evolved into animals.
“Regardless of the gait Tiktaalik used, it’s clear that the emphasis on hind appendages and pelvic-propelled locomotion is a trend that began in fish, and was later exaggerated during the origin of tetrapods,” Shubin said.
so now they want to tell us we evolve from a fish?
how do you go from monkey to fish?
Mitch's relatives?

My grandpa was fishing on a golf course one time and he cought a fish that had human like features. I couldnt tell but maybe there are some genetical similarities though...
Here is a pic of my grandpa...

This is a scientists way of saying we keep making up to hide the fact that we don't know what the we are talking about.“Previous theories, based on the best available data, propose that a shift occurred from ‘front-wheel drive’ locomotion in fish to more of a ‘four-wheel drive’ in tetrapods (four-footed animals),” said co-author Neil Shubin, who is a professor of Anatomy at the University of Chicago. “But it looks like this shift actually began to happen in fish, not in limbed animals.”
Ah, Jesus Christ.
1) This isn't really that new. This is just a much better fossilized skeleton that has been previously found, which is very cool. Scientists are not "now" telling us we evolved from fish. We've known that all along.
2) We *all* came from fish, so we went from fish to a monkey-like ancestor to us, not the other way around.
I know here on ST y'all have formed this weird little club to support each other, but, really, for most people, this news is not disturbing. It's just science, and most scientists are not out to get you. I'm only posting this one post, because I know from past experience that it doesn't matter how brilliantly and patiently I explain evolution to you, you won't read what I write and you will not believe the scary science lady because of your bizarrely insecure faith.
It's one thing to post a Bull topic for no reason, it's another to not support the very something you took the time to make a topic about in the first place
I trust scientists as experts far more than delusional quack posters on basketball message boards. You know who you are.
Science for all its faults, is still far better than the alternative, and the war on science being waged by ignorant s in the world should alarm anyone.
Feel free to keep posting easily debunked and irrational arguments to support your delusions. It *is* entertaining.![]()
Why do you need to trust in something to explain why you exist?
As usual, you have me the in the crushing grip of reason.
The lengthy, well-thought out arguments are just too much for my poor intellect to grasp, and I just can't keep up.
(rolls eyes)
Not sure exactly what you are getting at here.
I would say that I don't look to science for metaphysical answers, if that is what you are driving at.
The empirical method is the only way, though, to get at any kind of verifiable truth.
ironic that the ignorant s are waging war through mechanisms that only science can provide![]()
Remove the Bolded parts of your reply and you will look smarter.
What proof you have?
