Slide1
1) What evolutionary force creates adaptations
A) mutation
B) genetic drift
C) selection
D) migrationSlide2
2) Adaptations are favored because
A) they help the species survive
B) they are more advanced
C) they create a balanced ecosystem
D) they promote the reproduction of the genes that code for them
E) all of the aboveSlide3
3) Independent contrasts
A) are used to ensure statistical independence of data points in comparative studies
B) require
phylogenetic
information about the group under study
C) are the differences between
taxa
that have arisen after the
taxa
diverged from a common ancestor
D) all of the aboveSlide4
4) trade-offs
A) affect virtually all traits
B) cause traits to be optimized not maximized
C) can be due to functional trade-offs and/or allocation trade-offs
D) all of the aboveSlide5
5) Should we expect all traits of all organisms to be perfectly adapted
A) yes, selection is sufficiently strong as to cause adaptation everywhere
B) no, because evolution is random
C) no, because environments change over time and because there are
phylogenetic
constraints and trade-offs
