Subject: Does our circadian cycle provide evidence we originated elsewhere?

Does our circadian cycle (sleep/awake cycle) provide evidence we 
originated elsewhere? Studies show humans fall into a greater than 24 
circadian cycle if placed in an environment with no time cues. The earth’s 
rotation is slowing down so it rotated much faster in the past. Any animal 
that evolved on this planet evolved during a time when days were 24 hours 
or less. If we evolved here wouldn’t it make sense that our natural cycle 
be 24 hours or less not greater than 24 hours? If tests have been done on 
other animals, especially primates, do they also fall into a greater than 
24 circadian cycle or are they less?
