Latest Neil Shubin Stories
While the fossil record has found that wrists and fingers have an aquatic origin, previous attempts to link fingers and fins have proven unsuccessful. Now, though, a team led by University of Chicago researchers has discovered the reason why: scientists were studying the wrong fish.
The evolution of hind legs actually began as enhanced hind fins, according to the newly discovered, well-preserved pelvis and a partial pelvic fin from Tiktaalik roseae—a 375 million-year old transitional species between fish and the first legged animals.
A SCUBA expedition in Australia and New Zealand to find the rare embryos of an unusual shark cousin enabled American and British researchers to confirm new developmental similarities between fish and mammals.
The genetic toolkit that animals use to build fins and limbs is the same genetic toolkit that controls the development of part of the gill skeleton in sharks.
Analyzing a fish/amphibian intermediate species or human beings' genetic code can uncover proof of evolution, scientists said at a Chicago gathering. Scientist Kenneth Miller, author of Finding Darwin's God, said at the 175th annual meeting of the American Association for the Advancement of Science that evolutionary evidence is apparent in the genetic codes of humans and non-human primates, the Chicago Tribune said Sunday. Miller theorized that both species share a number of so-called...
Some 375 million years ago, a unique fish existed with features in its head that helped pave the way for vertebrate animals to live on land, scientists said on Wednesday.

Even before they are born, all people carry genetic baggage, genes that were useful to distant, non-human ancestors but are hopelessly outdated, even harmful, to humans as they live today.
Fossils of a 375 million year old species of ancient fish found north of the Arctic Circle fill an evolutionary gap in the transition between water and land animals, scientists said on Wednesday.
