If chimpanzee and human genomes differ only about 1.3% at
the level of DNA base pairs, how can we explain dramatic
differences in appearance, behavior, cultures, and so on
between humans and chimps? - correct answer Important difference
exist in the expression of the genes in the humans and chimps
The primary process responsible for the adaptive modifications
that occur in populations of organisms over geological time is -
correct answer Natural Selection
The wing-ed-ness of a bat wing and hummingbird wing are
probably products of - correct answer convergent evolution
Synapomorphies are very important traits in phylogeny
inference. Which of the following statements is correct? - correct
, BIO 322 EXAM 1
Synapomorphies are derived traits inherited from a
answer
common ancestor. AND Synapomorphies help identify
monophyletic groups.
The uses of phylogenies include all EXECPT? - correct answer
Showing natural selection in action
Phylogenetic conservatism is - correct answer Probably the result of
complex systems of genetic expression becoming coadapted
and so imburdened as to prevent subsequent mutations that
would change conservative features from being beneficial
Which source(s) of data do evolutionary biologist use to test
their hypothesis? - correct answer Molecular data, Morphological
and behavior data, Data from the fossil record.
(all are correct)
Darwin's hypothesis of common ancestry with branching
descent explains - correct answer The history and patterns of life's
diversity, the hierarchical patterns of similarity observed in
nature, varieties need within species, nesting within genera
