Fossil spills the secret of transitional link from fins to feet

The newly found fossils of a 375 million-year-old life form give researchers a crucial clue in the transitional link from fins to feet.

This also gives occasion to feel qualms about the famous hypothesis that the rear appendages were created just after living beings started moving towards land from the sea.

Researchers say they found the generally saved pelvic blades from a toothy flap fined marine life form called a Tiktaalik roseae. The University of Chicago Medical Center stated that living beings could grow up to 9-feet since a long time ago, chased in shallow freshwater and, resembled a hybrid of a fish and a crocodile.

The reason this life form is truly intriguing is that its the best illustration of a transitional animal groups between fish and the tetrapods who existed ashore. The Tiktaalik roseae had both gills and primitive lungs, and additionally had shoulders, elbows and wrists extensive and solid enough to help itself ashore.

Neil Shubin, Phd, Robert R. Bensley Distinguished Service Professor of Anatomy at the University of Chicago explained that the last hypotheses, in view of the best accessible information, recommend that a movement happened from `front-wheel drive' velocity in fish to a greater extent a 'four-wheel drive' in tetrapods,
