Phylogenetics and molecular evolution lie at the heart of understanding the origins and diversification of life. By constructing phylogenetic trees, scientists map the evolutionary relationships ...

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. Receive emails about upcoming NOVA programs and ...

Phylogenetic analysis explores the evolutionary relationships between organisms and is a vital foundation for microbial studies. The development of reliable phylogenetic trees is an important step in ...

From quantum computing to deep learning and ancient protein analysis, scientists are revolutionizing how we reconstruct the tree of life. Modern phylogenetic methods now merge molecular, morphological ...

The new model focuses on phylogenetic diversity, which is very different from counting species, today's standard measure of biodiversity. The same number of species (three blue circles) can have a ...

In biology, phylogenetic trees represent the evolutionary history and diversification of species -- the ''family tree'' of Life. Phylogenetic trees not only describe the evolution of a group of ...
