HELP PLEASE !!!

Answer 1

Lines of evidence from many fields of study, from fossils to DNA sequences, have been important in developing evolutionary theory. Why is it important to have supporting evidence from a variety of fields?

It lends strength to the argument if evidence from a diversity of fields results in the same conclusion.

Asking scientists from a variety of fields to test the ideas means more scientists will take an interest in promoting the theory.

If a theory can encompass many different fields of study, then financial funding for future testing of the theory would be easier to attain.

It is unlikely that scientists will disagree with evidence collected within their own fields, so everyone would find something to agree with.



As hominids evolved, their litter sizes decreased and their gestation period increased. Which of the following inferences can be made based on this observation?

Reproductive success would increase, since mothers had to carry fewer offspring.

Hominids would have less difficulty finding mates, since competition is reduced.

Maternal care for offspring would increase due to a greater investment to protect.

Offspring would likely migrate in order to expand their territory and find mates.
