A phylogenetic tree (commonly known as an evolutionary tree or a phylogeny) is a diagram with branches that displays the evolutionary relationships between different biological species.

Phylogenetic trees derived from phylogenetic analyses depict that the first eukaryote, referred to as thelast eukaryotic common ancestor (LECA), is believed to be the last common ancestor of all eukaryotes. The first eukaryotes would have been likely protists orprotist-likeunicellular eukaryotes that ...
If a group of organisms falls into this category, this is known monophyly or a part of a monophyletic clade. Concerning monophyletic grouping, it is important to understand the relationships between living things and the classification of the organisms. Phylogenetic Trees A cladogram or phylogenetic...
Phylogenetic trees based on genetic data cannot reveal much about what might have caused adaptive radiations or extinctions. Careful examination of fossils combined with an understanding about what Earth's environment was like when these fossils were living can be used to infer what might have precip...
What are phylogenetic trees used for? Despite the fact that modern taxonomists have abandoned the Kingdom Protista, the term "protist" persists in the biological literature. Explain the current meaning of the term protist and give several specific examples. ...

phylogenetic treePhylogeny based on differences in the protein sequence of cytochrome c in organisms ranging fromNeurosporamold to humans. The greater the differences between the DNA of two living species, the more ancient the split from their common ancestor. Studies show that theseaccumulateddifference...
