Examine the phylogenetic tree above; Which of the following represents paraphyletic group? Group 3 Group 2 Group 1

Define phylogenetic classification system?

Identify the following in the sample cladogram below: plesiomorphy, symplesiomorphy, synapomorphy, autapomorphy, basal taxa, derived taxa.

Describe two reasons why it is important to society to study phylogeny and systematics.

Monophyletic groups are desirable in classification as they Select one: a.reflect evolutionary relationships b. minimise name changes from old to new classifications c. result in fewer groups and are therefore more parsimonious

A B C D E F G DEFG Which of the following forms a monophyletic group? (see figure) D, E, and F E, F, and G C and D A, B, and D

Which of the phylogenetic trees below represent the same evolutionary relationships? Tree 1 Tree 2 Tree 3 D В D G ·E O Tree 1 and Tree 3 O Tree 1 and Tree 2 O Tree 2 and Tree 3 All three represent the same relationships O No two trees represent the same relationships

What is a clade?

Why would it be nice to have classification reflect phylogeny accurately that is, to only name monophyletic groups
