A classic question in biology is whether evolution is entirely random or, can it follow predictable patterns. This question was popularized by the famous paleontologist and science communicator ...

The comparative analysis of primate genomes within a phylogenetic context is crucial for understanding the evolution of the human genetic architecture and the inter-species genomic differences ...

PBS science strand “Nova” is set to explore the “epic journey of life” in a new series about evolution. “Nova: Evolution” is a five-part series from the GBH documentary unit together with the BBC and ...
