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.
