Evolution and phylogeny

A genome can inform life scientists on how a species has evolved over time. Phylogeny studies the phenotypic and genetic closeness of species, displaying the evolution of life forms as phylogenetic trees.

Bioinformatics tools are able to read a species’ genome, and thereby understand its evolution and build phylogenetic trees. In this way and as an example, life scientists have acquired a greater understanding of human migration in the past, the genetic closeness of hens and dinosaurs and the evolutionary history of grass.
