Evolution happens every minute and although we might not acknowledge it but it is happening every day in our life. Going reverse, scientists have come up with a conclusion that we i.e. humans get their legs from fishes.
AS WE know, change is the only constant in life and evolution has been happening for millions of years now. Although no one has ever lived to see it actually happen it is a common knowledge now that humans have evolved from Apes. However, in a latest study, quite contrary to popular perception, part of our evolution has been from fishes - particularly three species of Australian fishes, including the lungfish, which was actually one of our ancestors.
Acoording to IANS, the research team led by Peter Currie and Nicholas Cole from Monash and Sydney universities respectively, found a connection between the muscles in the pelvic fins of the fish and the legs of humans and other bigger animals. They say that thanks to these fishes legs in animals evolved and these fishes are actually the ancestors of the distant species that took a step on land some 400 million years ago.
Although there's no hard-hitting evidence as to our 'fishy' ancestorship, these fishs was surely the first to have a pelvic muscle that eventually became the hind leg and then legs of humans. Scientists have always known about lungfish, the ancestors of the tetrapods who could live on land and breath. Since Australia is home to three remaining lungfishes, hence it was easy for the researchers to test their study.
To test the evolution of the pelvic muscles in fishes to legs in humans was only possible with the help of live fishes and since not a lot was known on the subject due to the unavailability of the fish - thus there was a gap in the knowledge. Now some more pieces of information is known and the pieces of the puzzle are fitting in.
