Twins were the norm for our ancient primate ancestors − one baby at a time had evolutionary advantages

Twins were the norm much further back in primate evolution, rather than an unusual occurrence worthy of note.

Modern humans overwhelmingly birth just a single child a rather large child with an even larger head.

The switch from birthing twins to singletons was critical for the evolution of large human babies with large brains.

The fact that women in the U.S. are routinely having kids in their 30s compounds this even further.

Women in the later stages of fertility that’s anyone over the age of 35 are more likely to have twins.

Despite these risks, our research shows that twins are a critical part of our genetic history.
