Study finds relationship between fins and hands
A team of researchers have found that there is a relationship between fins of fish and hands of human beings.
There has been a lot of speculation whether modern hands are related to the fins of fish. The latest study shows that modern hands are related to the fins of fish are indeed related. The team studied the genetic sequence of an unusual freshwater fish with that of mice. They found that genes involved in the development of the mice's hands and feet were also involved in the development of fins of fish.
"Fossils show that the wrist and digits clearly have an aquatic origin. But fins and limbs have different purposes. They have evolved in different directions since they diverged,"Neil Shubin, an organismal biologist at the University of Chicago, said in a statement.
Shubin and his colleagues found fossil of species called Tiktaalikroseae in 2004, which had both front and back legs and lived about 360 million years ago. Since then several researchers are seeking to understand the relationship between funs of fish ancestors and limbs of land animals.
The study indicates that fins of fish ancestors evolved into the limbs of modern land animals.
