Primates
The two suborders of primates that are recognized today are Strepsirrhini (lemurs and lorises) and Haplorrhini (tarsiers, monkeys, apes, and humans). The taxonomy of primates is an issue that is not resolved and has undergone many revisions over the years. Our Primates category attempts to deal with questions about primate species and subspecies described prior to and since the latest revisions.

What evidence shows that the kingdom Protista have a common ancestor with plants?
Many protista contain chloroplasts.
yes the homo-sapiens were much better adapted to life on earth and evolved much faster then all other homo species.*read Charles Darwin theory of evoloution.
Opposable thumbs, depth perception, peripheral vision, and limbs.
How would you describe a spreadsheet?
quantitative tool wherein data in cell locations are placed in rows and columns in matrix format. That makes data easy to structure. Rows and columns can be individually designed. Cell contents can be numeric data, alphanumeric data, or algorithms.
Are all known hominids are direct ancestors of modern humans?
Yes.Humans are direct ancestors of homonids.In fact the first humans appeared at 30,000 BC.That is just at the end of the Ice Age.Well,Neanderthals were the ones who appered in 30,000 BC.I think the first actual Homo Sapiens [Humans] appered 14 million years ago.But did you know that Homo Habillis [24 million years ago to 19 million years ago]Were the first species to use tools as rocks,wooden knives,Pots,.Another species[19 million years ago to 17 million years ago] was the first to ever make and discover fire.There is a lot of neat things about evolution and prehistoric times.Now,these facts that you just read are not ACTUALLY RIGHT.They are just the little basics of human evolution.
If a man evolved from monkeys and apes why do you still have monkeys and apes?
- Many people believe that man did not evolve from apes at all, we were created by God in His own image. That God gave man a human soul that makes them individual.
- The only other option is a theory called evolution, by which over billions of years, the whole earth and everything in it was formed by hydrogen, which spread through the universe at the Big Bang, an explosion in which the hydrogen was formed.
- Human beings (homo sapiens) related faintly related. Humans and other apes might share a common ape or ape-like ancestor.
- A species only evolves to help it in its survival. The apes' ancestors could survive being an ape so they didn't continue to evolve, whereas our ancestors kept evolving to help them stay alive. Survival of the fittest is what drives evolution, and our ancestors just happened to "need" evolution more than the apes. Evolutionary process is performed by mutations, which are usually harmful or fatal. For evolution to occur, an incredible chance happened so that the mutation would not harm or kill the new creature.
- Apes and humans evolved from an unknown common ancestor. This ancestor split up and evolved into different species, one became erect and the other continued as it was.
- Humans didn't evolve from apes; rather, we and apes evolved from a common ancestor (who is no longer with us, we have no fossils proving this fact, but we believe it anyway). The relationship is more like cousins than parent-child.
- By a very great chance, humans developed a brain that allows them to think, love, and be individual persons. Christians call this a soul. It elevates us above beasts.
- There are still apes because some apes did not evolve into people. If rocks are crushed into stones, why are there still rocks? There are still rocks because some rocks did not get crushed into stones.
- Different species have evolved according to the conditions and ecological niches they find themselves in. Speciation occurs when a subtle change confers an advantage on a given population.
- It is also important to remember that not all changes of animals mean it has evolved. Animals have great genetic variety, to suit different environments. This is called natural selection.
Let's think of a simple example of changes by natural selection:
If the world were suddenly covered in snow, and polar bear-type predators invaded everywhere, it stands to reason that they'd be more likely to eat dark-colored animals which they could see more easily.
That would give an advantage to animals which, by chance or design, happened to be white. Animals of a usually black type which happened by chance to be *partly* white might also escape the bears. They would then be most likely to breed, passing on the white genes to their offspring.
Over time, through breeding in a selective group, all animals would become white, as the ones least suited to their environment were weeded out. Some species which were unable, by chance, to adapt, would go extinct as the polar bears ate the lot of them.
So, humans have evolved in a different way than chimps, gorillas and orangutans because the requirements of the environment we found ourselves in were different. It was an advantage for us to go in the direction we went, just as it was for the other apes.
Evolution works randomly. Natural Selection works towards the animal's specific needs. The mutation to create more hair in a cold environment would be in a specific population so some humans in the group would have more hair by nature (genetically). These individuals would in turn have a greater chance for survival in the cold environment. As they are selected for by nature their percentages will increase. More of the hairier humans will survive to reproduce and their children will be genetically driven to be hairier. That is just one of the marvelous and logical ways evolution in our nature world occurs.
- Natural selection is variations in genetic genetic variety that changes a species within itself. For instance, say a tribe of fair skinned people traveled to a very hot climate, those people with darker skin would be more likely to survive thereby passing on there dark skinned genes and eventually weeding out the fair skinned people.
- Evolution only occurs when it is necessary. Some apes evolved into man because either they moved to a new environment or their existing environment changed, making evolution necessary for survival. So, the apes who needed to adapt to their new environment through evolution to survive either did so or were wiped out (apparently, they changed, creating the human race), or stayed in a friendly environment, making evolution unnecessary and therefore, nonexistent (the apes in these conditions remained apes).
- Technically, humans are apes.
- Science never said humans evolved from apes. Science said that humans and apes evolved from a common ancestor. That makes humans and apes related species. And those who abhor the idea of humans evolving from apes may be even more incensed to learn that we did not evolve from apes, but from a more primitive species.
Which structure in primates enables them to develop complex social systems?
A well-developed cerebrum is the structure in primates that enables them to develop complex social systems. Cerebrum is Latin for brain.
What are hot compresses used for?
Hot or warm compresses are useful for soothing muscle aches and treating abscesses.
What college did Jane Goodall go to?
Jane Goodall earned a doctorate in ethology from Darwin College, the University of Cambridge in 1964. (from http://en.wikipedia.org/wiki/Jane_Goodall)
What are the animals that gorillas kill?
Gorillas are not carnivores, so they do not have a strong predator instinct or the instinct to kill animals. Ninety-nine percent of the time a gorilla would rather be left alone and leave another animal alone than be wanting to kill it.
A gorilla will only kill out of defense. For instance, a male silverback will defend his group with his life, and will either kill or be killed or fight until the threat runs away in order to defend his family.
The estimated age of Ardi, a female Ardipithecus ramidus, is 4.4 million years. The skeletal remains of the hominid were unearthed in 1994 in Ethiopia, and more than 110 separate bones or fragments have been recovered.
What Homo species evolved 200000 years ago?
200.000 years ago is the approximate starting era of what is known as the modern man, or Homo Sapiens if you like.
Skeletons dated that far back are showing signs of evolution towards "ours" .
