This important study addresses the timely and interesting question of how itaconate generation emerged in evolution, using taxonomic analysis of the gene and enzyme cis-aconitate decarboxylase (CAD).

WHATEVER may be the opinions of individual investigators, or even of groups of investigators, as to the status of the ancestors of the eutherian mammals, there has not as yet appeared any conclusive ...

Studying the organization of genes within genomes across broad evolutionary timescales can advance our understanding of the evolution of traits and clades. We have used a network approach to ...

The URIs are stateful! You can always use the same link to recreate the exact parameters. Specifically, the URI is a Base-64 encoded query string of what is loaded asynchronously.

Why were the sauropod dinosaurs able to get so much larger than today's terrestrial animals? Scientists believe they may have now solved this puzzle. According to new research, Jurassic fast food ...

The evolutionary theory of aging predicts that species will experience delayed senescence and increased longevity when rates of extrinsic mortality are reduced. It has long been recognized that birds ...
