Question

b. humans and Neanderthals interbred

c. humans and Neanderthals are 98.8% genetically identical

d. humans are direct descendants of Neanderthals

e. there is a 5% difference in the coding regions of the human genome vs. the chimpanzee genome

36. The observation that SNPs account for most of the differences in the coding regions between the human and chimpanzee genomes suggests that ____.

a. the two genomes are too different to suggest an evolutionary relationship

b. Neanderthals descended directly from chimpanzees

c. small changes in amino acid sequences account for big differences in phenotype

d. most of the differences in phenotype are due to DNA sequence changes

e. humans descended directly from chimpanzees
