CLADISTICS

Which encircled area shows a clade?

• A

• B

• C

• D

What correlation can be found between the number of sequence differences and the time since the diverge from a common ancestor?

• The geological period in which the species in the clade diverged from their common ancestor

• The sequence of differences accumulate gradually since the divergence from common ancestor took place.

• The number of characteristics the species have in common as time goes by.

• The number of mutations that have occurred since the species shared a common ancestor

The rate of mutation is more frequent in

• Gene sequences

• Non-coding DNA

• Oncogenes

• Hox genes

What is the difference between convergent and divergent evolution?

• • Convergent evolution shows analogous structures. Divergent evolution demonstrates homologous anatomical structures.

• • Convergent evolution shows homologous structures. Divergent evolution demonstrates diverse anatomical structures.

• • Convergent evolution shows homologous structures. Divergent evolution demonstrates analogous anatomical structures.

• The presentation got me all confused.

A molecular clock can be used to

• Estimate the time from the divergence from the common ancestor according to the similarities in phenotypes.

• Estimate the time from the divergence from the common ancestor according to the differences between proteins.

• Tell the time.

• Estimate the time from the divergence from the common ancestor according to the differences between base pairs.
