9. Mirror Neurons Associated with Viewing Behaviors (American Psychological Association)
   "Then Greenfield learned that researchers had found mirror neurons--nerve cells that fire when primates not only produce a goal-directed action but also watch someone else produce the same action--for manual actions (such as grasping) in the F5 brain area in monkeys, a Broca's homologue, and in Broca's area in humans." 12-05.

10. Australopithecus (Mr.Donn.org)
    "About this same time in history, around 3 million years ago, the higher primates, including apes and early man, first appeared. There was a difference between apes and man. Human-like hominids could stand upright. Apes could not. Their hands were different, too. Ape hands were made for climbing and clinging. Early man's hands were jointed differently, which allowed them to not only use tools, but to make tools." 03-06

11. Baboons (A-Z Animals)
    "Baboons are medium sized primates found in Africa, and are best known for their bright behinds!"
    
    "Baboon live together in troops with only one dominant male baboon for every troop. The other up to 50 remaining baboons are females and baby baboons, that are either female or not old enough to survive without the baboon troops help." 01-09

12. Important Transitional Fossil Found (Time.com)
    "The fossil is so perfectly preserved because Ida probably died quickly and nonviolently; her resting place was an abandoned quarry called the Messel Pit, near Frankfurt."
    
    "The second reason the discovery is so important is its age. Ida — her scientific name is Darwinius masillae — dates to about 47 million years ago, when temperatures were warmer than they are today and when mammals underwent a burst of evolutionary diversification. In particular, that's when primates began splitting off into two branches. One became anthropoids, whose descendants are monkeys, apes and humans. The other turned into prosimians — lemurs and their kin."
    
    "Ida is intriguing because she has some characteristics of both branches, which suggests that she could be a transitional animal that gave rise to the anthropoids and, ultimately, to us." 05-09

13. -Planet of the Humans, Not Apes (CNN News)
    "The World Wildlife Fund (WWF) estimates that there are at most 500,000 great apes left living in the wild—about the population of Fresno. (Great apes include gorillas, orangutans, chimpanzees and bonobos.) We've whittled down the populations of our simian cousins through deforestation—which destroys their habitat—and through hunting, including for meat. Even infectious disease is a major risk—it's thought that 25% of the world's gorilla population has died because of Ebola, a deadly fever that currently poses a much greater threat to apes than it does to us. The nonhuman primates look scary in Rise of the Planet of the Apes, but in reality, our closest cousins are in deep trouble. 'The current reality of great ape populations is more of a tragedy than an action thriller,' says Richard Carroll, the head of WWF's Africa program and a gorilla expert. 'If we as humans can't protect our nearest living relatives, then we've failed as a species.' "
    
    "Meanwhile, there are nearly 7 billion humans living on every corner of the planet. It wasn't always this way. More than 10,000 years ago, before the development of agriculture, there may well have been more apes than humans—and at the time, we may not have looked like a very good evolutionary bet. Now humans utterly dominate the world, leaving less and less room and resources for wild animals. The hot new term for our current geologic era is the Anthropocene, which reflects the fact that human beings—through carbon emissions, resource use and simple numbers—are now the major force on the planet, capable of changing the genome and the climate alike. It's still a Planet of the Humans—and that's still bad news for the apes." 08-11

14. Changes in Social Status Seen in Genes of Monkeys (New York Times)
    "Social stress is known to have adverse health effects on both humans and primates."
    
    "Now, researchers report that it also affects the immune system of female rhesus macaques at the genetic level."

15. Brain Implant Improves Thinking in Monkeys (New York Times)
    "Scientists have designed a brain implant that sharpened decision making and restored lost mental capacity in monkeys, providing the first demonstration in primates of the sort of brain prosthesis that could eventually help people with damage from dementia, strokes or other brain injuries."
    
    "The device, though years away from commercial development, gives researchers a model for how to support and enhance fairly advanced mental skills in the frontal cortex of the brain, the seat of thinking and planning." 09-12

16. -Studies: Two Disagreeing Explanations on Monogamy (Healthland.Time.com)
    "According to one [study], primates are monogamous so that nonrelated males don’t kill their babies. According to the other, that’s hooey; animals are monogamous because it was the only way they could guard their mates and thus their breeding rights."
    
    "Both studies suggest that the third theory often advanced for the development of monogamy — in which males can assist in raising of the young — is much less likely. Rather than a cause of monogamy, such paternal assistance is probably a consequence of the mate-for-life scenario." 07-13

17. A Bigger Brain Is Not Necessarily Better (Gizmodo.com)
    "Cows, for example, have larger brains than just about any species of monkey, but unless they're very, very good at hiding it, cows are almost certainly less cognitively capable than most, if not all, 'lesser-brained' primates."
    
    "The average human brain weighs in at around 3 pounds, and an elephant brain can weigh close to four times that much, but the biggest brains of all come sperm whales, and weigh an average of 17 pounds." 04-16

18. -Ebola Virus Disease (World Health Organization)
    "Ebola virus disease (formerly known as Ebola haemorrhagic fever) is a severe, often fatal illness, with a death rate of up to 90%. The illness affects humans and nonhuman primates (monkeys, gorillas, and chimpanzees)."
    
    "Infection occurs from direct contact through broken skin or mucous membranes with the blood, or other bodily fluids or secretions (stool, urine, saliva, semen) of infected people. Infection can also occur if broken skin or mucous membranes of a healthy person come into contact with environments that have become contaminated with an Ebola patient’s infectious fluids such as soiled clothing, bed linen, or used needles." 10-14
