1
Q
clade
A
consists of all of organisms that have evolved from a common ancestor
2
Q
cladogram
A
tree diagrams that show clades
3
Q
how are cladograms most often constructed?
A
using molecular evidence (non-coding DNA, gene sequences, amino acid sequences)
4
Q
serves as a good biological “clock” to determine approximate when species diverged?
A
Mitochondrial DNA
5
Q
what can also be used to determine what species are part of a clade?
A
The amino acid sequences of proteins
6
Q
sister groups
A
Two descendents that split from the same node
