The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

LOGAN, UTAH, USA – Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether ...

A significant study has mapped the genetic complexity of Populus cathayana, an ecologically and economically valuable poplar species. By creating a detailed genome assembly and analyzing genetic ...

Ferns, defined by large genomes, high chromosome counts, and pervasive aneuploidy as well as intraspecific polyploid complexity, diverge significantly from the classical genetic theories and ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...
