Play NOVA's Evolution Lab to explore the tree of life and become an expert in phylogenetics—the study of the evolutionary relationships among species.
Temple University researchers have assembled the largest and most accurate tree of life calibrated to time, and surprisingly, it reveals that life has been expanding at a constant rate.
Very little is known about the 'primordial soup' from which life is meant to have sprung , but a study from the University of Illinois shone a surprising light on the mystery.
The central ideas of evolution are that life has a history — it has changed over time — and that different species share common ancestors. Here, you can explore how evolutionary change and evolutionary relationships are represented in "family trees," how these trees are constructed, and how this knowledge affects biological classification. You will also

The process of evolution produces a pattern of relationships between species. As lineages evolve and split and modifications are inherited, their evolutionary paths diverge. This produces a branching pattern of evolutionary relationships. By studying inherited species' characteristics and other historical evidence, we can reconstruct evolutionary relationships and represent them on a "family tree," called a phylogeny.

This freshly drawn Tree of Life contains a new branch full of microbes — which appear to dominate Earth’s biodiversity. How did we miss that? TED Fellow Hélène Morlon explains.

Biology’s tree of life has morphed from the familiar classroom version emphasizing kingdoms into a complex depiction of supergroups, in which animals are aligned with a slew of single-celled cousins.
