One Problem Commonly Experienced in Phylogeny Reconstruction Arises When Two

question 23

Essay

One problem commonly experienced in phylogeny reconstruction arises when two or more of the groups being compared have accumulated far more genetic changes (mutations) than the others in the comparison. This situation often results in a phenomenon known as "long branch attraction," where the highly mutated lineages end up grouping together in a phylogenetic analysis even if in fact they are distantly related. What do you think causes long branch attraction? How might it be compensated for?
