"However, the human brain and sense organs have not had evolutionary time to change responses to these types of sense cues," Loucks wrote in his study.
A room big enough to hold 150 had evolutionary biologists spilling into the hallways, eager to hear a discussion of why their field was so poorly understood and often so poorly taught -- and what they could do about it.
Most zoologists recognize the trilobites, chelicerates, crustaceans, and myriapods as four major lines of arthropod evolution, but there is little agreement as to how those lines are related to one another or, indeed, if they had evolutionary origins independent from those of the annelids.
Evolutionary biologist H. Martin Schaefer of the University of Freiburg in Germany and colleagues wondered whether the breeding separation had evolutionary consequences.
Earlier studies, like this one, included far fewer individuals, which made it difficult to draw firm conclusions, such as whether an extra gene in a human had evolutionary significance or was just a personal peculiarity, says Redon.
Loci OPA1-3 and Flank-F3 had evolutionary histories of recombination.
