Benefits include the (relative) certainty of access to the partner’s reproductive potential, but the chief disadvantage is that access to other potential partners is strongly diminished, particularly in those cases where males exhibit strong mate-guarding behavior.

Why do females choose mates?

Can animals mate with different species?

When organisms from two different species mix, or breed together, it is known as hybridization. The offspring that are produced from these mixes are known as hybrids. Hybrids occur in the natural world and are a powerful evolutionary force.

What conditions promote the evolution of monogamy?

Monogamy may evolve when the cost of acquiring mates is very high, when females have the ability to restrict male behavior, or when offspring survival requires more intensive care than can be provided by a single animal.

When did monogamy become a thing?

From what they found, they concluded that hominids 4.4 million years ago mated with many females. By about 3.5 million years ago, however, the finger-length ratio indicated that hominids had shifted more toward monogamy. Our lineage never evolved to be strictly monogamous.
