Postby handbanana » Mon Oct 15, 2007 5:50 pm

How should I draw a phylogenetic tree for the following creatures:

Dogfish shark, rat, snake, frog and an earthtworm.

what would be the main characteristcs combing the the five of them? which would be the closest?

Thanks!

Look for their close relationship with each other.
Comparative anatomy helps.
