Using DNA to study species relationships

Molecular scientist Alfried Vogler compares the DNA of insects to help him understand how species are related to each other. 

Join Alfried in this video as he explains how his research is helping to build a tree of life, which will allow us to understand the living world in more depth.

'One of the most amazing things about the living world is that all the species in existence today are derived from a single common ancestor. Gradually lineages diversified and branched out in a tree-like shape and give rise to all existing species today,' says Alfried Vogler.
