Notice the little numbers next to every internal node in the phylogenies. These are bootstrap values. Use the entirety of human knowledge (e.g. Google) to learn what a bootstrap value is. In your own words (less than 100 words), explain what a bootstrap value is and why the information it provides is useful.
Phylogenetic trees are constructed based on parsimony the idea that the simplest answer is the misy likely. Explain why a parsimonious tree is a likely but not the only possible answer when depicting evolutionary relationships.
Which of the following features is found in a rooted tree but not in an unrooted tree?a. Terminal nodesb. Internal nodesc. A common ancestor to all other nodesd. Branch lengths that represent the amount of evolutionary divergence between nodes
