Can Gorillas cry?
Visibly upset, the western lowland gorilla kept signing the words “sad, frown, cry, bad” and cried out with a hooting sound she made as a baby while left alone in her cage at night. “Those are the only times she gives that cry,” her longtime caregiver, Francine “Penny” Patterson, said in 1985.

Do fishes cry?

Why are humans pregnant for so long?
An anthropologist suggests that the length of human pregnancy is limited primarily by a mother’s metabolism, not the size of the birth canal. The research challenges the long-held notion of an evolutionary trade-off between childbirth and a pelvis adapted for walking upright.

Are humans the smartest animal?
Despite the prevailing belief that humans dominate the animal kingdom when it comes to smarts, we’re actually ranked as the third-smartest species on the planet — at least according to Douglas Adams, author of “Hitchhiker’s Guide to the Galaxy.” But joking aside, there is something to be said for Douglas’ idea, at …

Why do only human babies cry?
Humans are kind of outliers in that human babies are just spectacularly helpless compared to the young of other species. … If pregnancy were longer, they simply would be too big for human bodies to give birth too. We are victims of our own intelligence/brain size. The crying is simply evolutionary process at work.
