In rhesus macaque troops, social hierarchy significantly impacts offspring welfare, as lower-ranking mothers like Dottie and Gypsy produce thinner, less healthy babies compared to higher-ranking females like Mitzi, demonstrating that maternal social status directly affects infant development and survival rates.

The day it fell with a thunder II - furry little balls π and their mothers π¨Added:
[music] >> A baby means everything to a female rhesus macaque.
Especially for one who has never experienced the joy of motherhood.
She will go to great lengths to get close to a baby for a cuddle.
Through this behavior, we can understand the social hierarchy within the troop.
For example, Dottie ranks above Lizzy.
But she is below her mother, Dorothy.
As a result, Dottie's daughter, Daphne, suffers the consequences of this ranking.
>> [music] >> Poor Daphne, now I can say she is so much thinner than Mitzi, even though she's one of the firstborns in this crop of babies.
Dorothy's meddling is taking its toll on this little girl indeed.
Dorothy's milk must be of much inferior quality. Oh well, it's a miracle that she had some milk in the first place.
Mitzi is just so much chubbier. Just look at that pinky foot of her.
Dottie is back with Daphne.
Even though she has a little girl of her own, she seems to be wanting another one, too.
What's happening? Why is she lying low all of a sudden?
I see. It's Barry, the regent and de facto alpha.
Just asserting his authority about.
And here's when age counts for something. Lizzie has lived long enough to know who a wannabe is.
Sad to see Grandy no longer takes the center stage anymore.
But life goes on just the same for our babies.
>> [music] [bell] [bell and music] >> Whoever it is, the row is over already.
One usually sees nothing by the time they turns around.
Now Gypsy and her family has pitched up.
These two are among some of the lowest ranking females in our gang.
And between these two, Gypsy is the lower one. I don't think there's anyone even lower than Gypsy.
>> I see why they are beginning to pop up one by one. Feeders.
Gypsy has got herself something, so Tabby was a bit jealous just now.
>> [music] >> Those feeders possibly didn't know they have done Toby a huge favor.
>> [crying] >> Like us humans, we treat [music] one another differently.
>> [music] >> Oops, poor Tazi has got too close to her baby sister to her mom's liking.
