But new research identifies the availability of "living space", rather
than competition, as being of key importance for evolution.

Findings question the old adage of "nature red in tooth and claw".


Professor Mike Benton, a co-author on the study, explained that

"For example, even though mammals lived beside dinosaurs for 60
million years, they were not able to out-compete the dominant
