This diagram is an example of a simple phylogenetic tree. In most cases, researchers draw phylogenetic trees in such a way as to record only those events that are relevant to a set of living taxa.

Thus, understanding the evolutionary history of living species amounts to understanding where on the tree of life these species' distinctive traits arose. Moreover, phylogenetic trees serve as ...

The Evolution Lab contains two main parts: Build A Tree: Students build phylogenetic trees themed around the evidence of evolution, including fossils, biogeography, and similarities in DNA.

They used Blomberg's K statistic to quantify tree growth phylogenetic signal (TGPS) values. The researchers used two long-term tree growth datasets, one monitoring the growth of 225 tree species ...

Mixodectes belonged to an extinct family known as mixodectids and lived during the Paleocene epoch. This geological epoch followed the Cretaceous-Paleogene extinction event that killed off non-avian ...

These organisms, named Prototaxites, lived around 420 million to 375 million years ago during the Devonian period and resembled branchless, cylindrical tree trunks. These organisms would have been ...
