New theory explains how fishes grew into amphibians

Washington: A small fish pond in the desert crawl drying stresses the theory that links fish amphibians, the study shows.

"This kind of courage in our hypothetical ancestor probably would not have survived the overwhelming odds of death in the trek to another decline in the pond," said Gregory J. Retallack, professor of geological sciences, University of Oregon, who led the study.

This scenario comes from the late Devonian period, about 390 to 360 million years ago, the late Harvard paleontologist Alfred Romer propounded, reported in the Journal of Geology.

Romer challenges the theory of survival of fish, Retallack said that the transitional fossils were not related to the drying ponds or desert, but were found consistently moist soil, forest, according to a university statement.

"Judging from where the fossils are found, the transitional forms between fish and amphibians living in forested areas. Our distant ancestors did not have as much or foolhardy opportunistic advantage of floodplains and lakes choked roots and logs for the first time in geological history," said Retallack.

"The legs proved to be comfortable negotiating obstacles, and a flexible neck woody allowed feeding in shallow water," he said.

"The hypothesis of a new forest, legs and neck, which distinguish salamanders fish, not due to reckless adventure in the deserts, but the newly developed habitat at the top were wet, wooded floodplains," Retallack said.

"The old soil and sediments fossils of transitional measures for places all over the world have a critical understanding of when and under what conditions the fish first walked on," he added.
