A remarkably diverse fossil ecosystem in central Colombia that preserves an unusual overlap between survivors of older Jurassic groups and newer Cretaceous lineages has led researchers at McGill University and the Centro de Investigaciones Paleontológicas (CIP) to recognize a new
A remarkably diverse fossil ecosystem in central Colombia that preserves an unusual overlap between survivors of older Jurassic groups and newer Cretaceous lineages has led researchers at McGill University and the Centro de Investigaciones Paleontológicas (CIP) to recognize a new pattern of large-scale evolutionary transition, one that does not include mass extinctions.

The genetic cost of being a lazy parent ... if you're a cuckoo finch
African cuckoo finches (Anomalospiza imberbis) are very deceptive birds, or at least the mothers are. They sneak into the nests of other birds, such as prinias and cisticolas, to lay their eggs, then slip away and leave the hosts to raise the chicks.
