And finally tonight, a story about a different kind of modern american family. A gorilla baby and some surrogate parents, ready to do anything they can. Here's abc's matt gutman. Reporter: How strong is the maternal instinct? We've seen gorillas groom their young, carrying them for their first 18 months, nursing them up to three years. So when this squirmy infant gorilla's mom rejected her last month at a texas zoo, they named her gladys. Flying her to the pry mat experts at the cincinnati zoo. There, humans, who you see giving her her daily checkups, will teach gladys how to be a gorilla. We've seen this before with orangutans, they're dna is so similar that humans often can take parental roles. It looks like gladys is playing "how big is the gorilla" but her surrogate us, wearing black to resemble her mom, are actually stretching her arms, just like you see hasani here. Doing tummy time is something gladys' biological mother would do, strengthening her neck muscles. And this tender hold, all part of preparing gladys for her new ride, adoptive mom's back, just like in the wild. And for that, gladys' six surrogates in ohio will wear these black hair vests. But you won't hear any cooing. Gorillas will do grunts like this -- Reporter: That's ron mcgill. He says baby abandonment is not unusual. It's not uncommon at all to be rejected. Because they have not been raised in an environment that shawn them to be a good mother. Reporter: The idea is to mother gladys until her mom takes her in in. Matt gutman, abc news, miami.
