With the advancement in science and with the growing technology, we are able to find out history in today’s World. We are able to gather information about various animal species as well as bird species. Not only this, details about human beings are also revealed with the help of old fossils buried under ground.
Out of such important details, one more important thing is found that development of human hands can be revealed through fossils of ancient fish species. Amazing. Isn’t?
So, there’s an ancient Elpistotege found in Miguasha, Canada which is providing with many hints about the development of human hands. The fossil is full 1.57 metres long fish, having its arm skeleton. The fossil was cleaned, prepared and then studied by various researchers. After the analysis took place, researchers detected a humerus (arm), radius and ulna(forearm), phalanges organized in digits (fingers) and wrist. Studies reveal that the fish can help us to reach the ancestors of tetrapods as well as human beings.
In Cloutier’s words, ‘It’s the first time in evolution of vertebrates that digits have appeared. The fossil is providing a missing link between a fish and the tetrapods and also a missing link between a fish and a hand.’
He also told everyone that ‘For years, thousands of visitors and many researchers walked through there, but this fossil was found by luck.’
‘Today we announce in the journal Nature our discovery of a complete specimen of a tetrapod fish called Elpistostege, which reveals extraordinary new information about the evolution of the vertebrate hand.’ says strategic professor in Palaeontology at Flinders University professor John Long.
The most excited researcher Cloutier wants to know how the discovery changes the picture of four limbed animals developed. Earlier fossils reveal the development of shoulder bones, then upper arms and then forearms.
In order to have a hand, the fish need to lose the fin rays and scales.
‘A fantastic discovery, an extraordinary achievement’. So many titles are given to this old fossil of Elpistotege.
