DNA analysis allows scientists to construct phylogenetic trees whose branches link together the relatedness of different organisms.
comprehensive guide to understanding phylogenetic trees and solving POGIL activities related to them. Chapter 1: Deciphering the Language of Phylogenetic Trees Before diving into POGIL activities, a strong foundation in phylogenetic terminology is essential. This chapter will clarify key concepts: Taxonomy: The science of classifying organisms.
The most important thing about POGIL activities is that students learn to construct their own content knowledge and develop important process skills through collaborative work. Posting answer keys to shortcut those important learning steps undercuts the whole point of using POGIL activities.
What is one advantage of building phylogenetic trees using DNA comparisons rather than anatomical features? It is more accurate because you have solid genetic data instead of mere observations.
Sometimes a cladogram is called a phylogenetic tree (though technically, there are minor differences between the two). In the past, biologists would group organisms based solely on their physical appearance.
a. How long ago did the common ancestor of all the organisms on this phylogenetic tree exist? b. Which two lines diverged 30 million years ago? c. List all modern descendants of the organism that was alive at the point indicated by the asterisk. 2 POGIL ™ Activities for AP* Biology 2.
