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.
This may be the reason why biologists have only in the last few decades come to develop a rigorous understanding of phylogenetic trees. This understanding allows present-day researchers to use ...
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.
“Understanding phylogenetic trees can be difficult, but we’re working to make it more accessible,” says principal investigator Chia Shen, director of Scientists’ Discovery Room (S ...
The same number of species (three blue circles) can have a very different phylogenetic diversity (the sum of the red branches on the tree connecting them) depending on how closely they are related.
The grey skulls were drawn from the sample used to model the skull of the virtual ancestor, shown in red. From left to right: KNM-ER 3733 (H. ergaster), La Ferrassie (H. neanderthalensis), Qafzeh ...
