Claim of reversed human evolution provokes skepticism, interest

Scientists' reactions have ranged from deep skepticism to interest in a report of a mutation that makes people walk on all fours, cited in a Turkish study as a possible instance of 'backward evolution.'

The bizarre case, reported last week in World Science, has also drawn attention from several scientists in Europe, some of whom are collaborating on a BBC documentary on it.

Three researchers with the University of Cambridge, U.K., and the London School of Economics wrote recently that the case could represent a 'rediscovery' of a walking style much like that of human ancestors.

This might help resolve a debate over how our forebears walked, they added. [News]
