  • This video talks about the procedures we use to reconstruct (estimate) phylogenetic trees from data that we have available. The criteria of parsimony, maximum likelihood, and Bayesian probabilities are contrasted. Lastly, the using of bootstrapping to indicate degrees of confidence in trees and portions of trees is described.

    Amazing video, it was very useful. Thank you so much!
    Can you please make a video explaining how the multiple sequence alignment affects the construction of the trees? And how we can improve it?

      I'll add that to the list. It may be a while though, but I'll keep this in mind for sure.

    Hello, Your video has helped me a lot. I want to ask you if you know how to make the relationship between 16s rrna gene tree and 23s rrna gene tree. Thank you so much

    How do you make a phylogeny where you know the MRCA? Do you write them on the node? Like, there has to be a way to show the exact evolutionary history of humans and all the Homo species. If we focused on that group, each terminal would be a different hominid, but Homo sapiens evolved from Homo erectus - but your description of phylogenies says terminal taxa are related?

    • @pleiotropy

      Yes, ancestors are often represented on the node and terminal taxa are related. Common ancestors would go on the tree where separate branches meet and the lineage back from there. The most recent common ancestor (MRCA) would be right at the split. Less recent common ancestors would be shown in the lineage leading back from there.
