Why is knowledge on phylogeny importantPhylogeny also is needed to understand when you're looking at divergent (new species in same clades evolving in parallel) or convergent (new pollinator / plant relationships built on shift in old abilities) evolutionary patterns.

Re: Why is knowledge on phylogeny importantThanks, that seems logical! It also seems important in a process called "pathogen spillover" (The transmission of infectious agents from a reservoir population (for example commercial bumble bees) to a sympatric wild population). This happens when commercially bred bumble bees are transpor...

Why is knowledge on phylogeny importantseems like an interesting and rather specific course, but I can speculate that the phylogeny of insect pollinators is important because understanding their evolution and ancestral species could give insight into the origin of relations that the pollinators share ...

Re: Why is knowledge on phylogeny important... large quantities of bark from this rare tree are required to produce enough taxol for a single patient. Through cladistic analysis, a phylogeny for the genus Taxus has been produced that shows Taxus cuspidata, a common ornamental shrub, to be a very close relative of T. brevifolia. ...
