It probably seems like menstruation would be a big pain for other primates, right? If you're reading this post and you're a woman, chances are you've had to deal with "Aunt Flow" since your junior high days or even earlier, month after tiresome month, so it makes sense that you'd want to know just how other animals, including our non-human primate cousins cope. After all, it's not like they can just run on down to the pharmacy for supplies. But the thing to remember is that in the past, and even in some other 'natural fertility' groups today, women would typically get married at a much earlier age and spend most of their adult lives either pregnant or breastfeeding, both of which cause what's known as "secondary amenorrhea" (no periods), so they would actually have way fewer periods over the course of their lifetime than we experience. It's the same for other primates (monkeys, apes, lemurs etc.). When a female primate ovulates, odds are she'll also mate with one or more males and become pregnant. Think about it - it's not like non-human primates (in the wild) have access to Birth Control. And, like I mentioned above, the entire time a primate is pregnant and lactating she also is not menstruating since both are metabolically draining on the mother. Infant primates aren't fed jars of mushy baby food or given bottle formula, either, so they pretty much have to rely on mom's milk until they can possibly begin to find food on their own -- especially since food sharing is pretty darn rare in other animals. All of this means that primate babies end up nursing for what would seem to us like a really long period of time. By the time a baby primate is weaning and its mum can ovulate and mate again, odds are she'll also have a line of eager males waiting in the wings to start the whole cycle over again, thus preventing menstruation. When implantation does not occur in a given cycle(recall that the length of a female's cycle varies both between species and also within the members of a given species), however, then the endometrial tissue might be reabsorbed (so there's no external bleeding) or shed (see Strassman, 1996), although few mammals have as much menstrual bleeding as humans. So, as you can see menstruation is not something that would pose a huge problem for most non-human primates because it would be a relatively rare event. Finally, the fact that women in developed countries today menstruate so much is, as you can see, certainly not the "ancestral" pattern, and has been linked to a rise in many types of reproductive cancers.
"How are different parts of the human brain similar to and different from the brains of other primates?"
well its the same color......
There are several differences between a human torso and the torso of other primates. The biggest one, though, is the size of the cranium. Because of the increasing size of the human brain it is by way larger than the cranium of other primates.
They aren't all non-human because humans are primates. Other primates include monkeys and chimpanzees and orangutans and gorillas, which are non-humans because they're not human.
By being more helpless at birth, and taking longer to reach any level of independence.
Other primates don't kill other things because they think it's "fun".
There is no much difference between the human birth and other primates. The process is basically the same.
The original and correct scientific name for humans is homo sapiens. Human beings are primates who belong to the family Hominidae. The human being can be distinguished by other primates from their bipedal locomaotions..
Sort of. They could always be replaced by that other primate ... a human.
A monkey is like a human it's just a little different! What do you think a monkeys like? I told you what I think there like!
Yes, they are. Other primates include lemurs, monkeys, apes, and humans. Yes, chimps are primates because of their characteristics such as forward facing eyes and nails instead of claws. They are of group Anthropoid and are even further dived in to the group Pongid (or great apes). They are like this because they are closely related to us in genetic material.
For human females, every 28 days. other animals on earth are different.
