The current brushing of cladistic techniques gives me an opportunity to pose a
question I have had for a while now. In a hypothetical lineage, Species A
evolves into Species B, which subsequently splits into Species C and D. A
cladigram might look something like this:
A B C D
\ \ \ /
\ \ V
\ \ /
How would one be able to go from this grouping of species, into a sense of the
evolutionary history of the group? Could one reconstruct the lineage of the
group from this diagram?
Believe me, I am not trying to reflame the Clade Wars. I simply wish to
understand the dynamics of how Cladistics work.
