Evidence Found To Support Nocturnal Bottleneck Theory
2012-11-01 09:33:36

April Flowers for redOrbit.com - Your Universe Online Most species of diurnal mammals have retained the imprint of nocturnal life in their eye structures since the age of dinosaurs. According to a new study from The University of Texas at Austin and Midwestern University, anthropoid primates - including humans, monkeys and apes - are the only groups that deviate from this pattern. This study is the first to provide a large-scale body of evidence for the "nocturnal bottleneck theory,"...

Physical anthropologist Chris Kirk has announced the discovery of a previously unknown species of fossil primate, Mescalerolemur horneri, in the Devil's Graveyard badlands of West Texas. Mescalerolemur lived during the Eocene Epoch about 43 million years ago, and would have most closely resembled a small present-day lemur. Mescalerolemur is a member of an extinct primate group "“ the adapiforms "“ that were found throughout the Northern Hemisphere in the Eocene. However, just like...

A fossil that was celebrated last year as a possible "missing link" between humans and early primates is actually a forebearer of modern-day lemurs and lorises, according to two papers by scientists at The University of Texas at Austin, Duke University and the University of Chicago. In an article now available online in the Journal of Human Evolution, four scientists present evidence that the 47-million-year-old Darwinius masillae is not a haplorhine primate like humans, apes and monkeys, as...

Climate provided refuge for diminishing population More than 40 million years ago, primates preferred Texas to northern climates that were significantly cooling, according to new fossil evidence discovered by Chris Kirk, physical anthropologist at The University of Texas at Austin. Kirk and Blythe Williams from Duke University have discovered Diablomomys dalquesti, a new genus and species of primate that dates to 44-43 million years ago when tropical forests and active volcanoes covered west...
