Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated. Sharks are egg ...

Convergent evolution, ... (CDS), the goodness-of-fit of the accepted phylogenetic tree with that of an alternative convergent hypothesis (in this case, ...

Researchers will reconstruct the process of evolution, determine relationships between species and build phylogenetic trees with greater accuracy thanks to new method for identifying extremely ...

NPR's Robert Siegel speaks with Jonathan Losos, author of the new book, Improbable Destinies: Fate, Chance, and the Future of Evolution, which explores the growing understanding of "convergent ...

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 ...

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 ...

Phylogenetic evidence from the authors' previous work demonstrates that carcinized body plans have evolved multiple times (indicated by the colored characteristics on branches). Carcinized clades ...

Convergent evolution is what we see when we observe that bats and birds have similar development of their arms into gliding wings, which initially allowed them to glide, and then to fly.

Convergent evolution is when similar features that have a similar form or function evolve in species from different periods or regions, despite the last common ancestor of the species not having ...
