What do phylogenetic trees illustrate? These diagrams don't just organize knowledge of biodiversity - they also show us that living species are the summation of their evolutionary history.

Intracellular endosymbionts that originally descended from free-living prokaryotes have been important in the evolution of eukaryotes by giving rise to two cytoplasmic organelles. Mitochondria ...

To help you explore this tree and understand the amazing mechanism behind it, we’ve created the NOVA Evolution Lab. Play this Lab and you’ll be on your way to becoming an expert in ...

I heartily recommend this book and found it a joy to read...The rich array of evo–devo research that is brought to bear in Quirks of Human Anatomy provides another independent line of evidence for our ...

Jack M Craig, Dr. Blair Hedges, and Dr. Sudhir Kumar, all at Temple University, have built an evolutionary tree that encompasses 455 primates, every species for which genetic data are available.

In this evolutionary tree, species A and B share a recent common ancestor. Species A is therefore most similar to species B. Species F and G also share a recent, common ancestor, however this ...
