Which came first in the fossil record — our thumbs or our shoulders?  Find out by visiting Evolution Mosaic, a new educational website about human origins.  This was Betsy Lawlor’s sabbatical project for 2008-2009.

The site address is http://elearn.mtsac.edu/elawlor/mosaic

Evolution Mosaic aims to teach the concept of mosaic evolution — different body parts evolved at different times due to different selective pressures — and to make it accessible to Grades 6 through college by nesting more complex material in pull-down panels.

I hope you enjoy it, learn from it, and share it with anyone you think might be interested.

Looking forward to your comments.
