Question

Need both answered  

Which of the following best describe(s) the molecular evidence used to assess the relationships among humans, gorillas, and chimpanzees?

a) All molecular data sets agree with the morphological data and support the hypothesis that humans and chimps are more closely related to each other than either is to gorillas.

b) Most data sets support the hypothesis that humans and chimps shared a more recent common ancestor than either did with gorillas.

c) The data are equivocal; we cannot rule out the hypothesis that humans, chimps,and gorillas diverged simultaneously from their most recent common ancestor 5-6 million years ago.

d) The majority of data sets support a human-gorilla common ancestor with chimps more distantly related.

Sarich and Wilson's 1967 analysis of evolutionary relationships among hominoid species:

a) Included mitochondrial DNA from the fossil remains

b) Three of the choices are correct

c) Suggested the date of the last common ancestor of humans and great apes was close to 5 million years ago.

d) Was the first time scientists acknowledged the close relationship between humans and apes.

e) Was based on a phylogenetic analysis of human and primate albumin protein sequences.
