My friends all say my sister is hot but i dont wanna tap that.why?

Children reared together tend to avoid erotic relationships. This has been observed in a wide variety of societies; in fact it is almost a human universal. The only time it is violated in a socially approved way are some very exceptional and stylised rules, such as brother-sister marriage in some ancient royal families.

The most plausible explanation is usually some variation of the Westermarck effect – named after the anthropologist who noted it in the late 19th century. The exact mechanism is still not established; it seems to be some kind of mental imprint that gets stuck in the brain from an early age. Kids don’t even have to be related – children raised in the same group tend to avoid relationships, even if there’s no biological connection.

Note that the rule isn’t 100% reliable, since there is a low but persistent incidence of brother-sister incest (and brother-brother or sister-sister, with homosexual siblings). So society seems to have re-inforced the underlying biological instinct with strong social sanctions – nearly every society regards incest as a disgusting taboo with heavy formal or informal penalties.

So all-up – props on having a hot sister, dude; but it’s natural, normal and pretty healthy you don’t want to nail her!

Given that every recorded culture which has ever existed has had forms of incest-avoidance, it is as universal as any "human trait" — so we can say with some justification that it is rooted in the biological.

There seems to be a very deep-rooted avoidance of being sexually attracted to (a) people you have been in daily close contact with since infancy, and (b) people who smell too much like you.Obviously this doesn’t hold true for absolutely EVERY SINGLE INDIVIDUAL under the sun, but there is still a distinct, noticeable, and measurable response in every culture.

It is very likely genetic:primates are prone to problems from inbreeding, so those individuals who didn’t mate with close relatives most likely had more robust and healthier offspring — and over time, those offspring, those "outbreeding" tendencies, and the genes for the instinct to avoid breeding with those close to you, will have come to predominate.In fact, we do see that with most primates — even bonobos avoid parent/child matings, for example, and they are famous for having sex with anything, anywhere, any time.

Psychologically, many people can be attracted to their siblings, but society frowns upon incest. On the biological side, such a union can produce offspring with numerous defects which inhibits a normal sex drive to some degree, but does not completely overpower the need to reproduce.

Biologically speaking, when two people who are so close in genetic relation elope they create an offspring of poor genetic health.

my friends telling me that we evolved from t-rex and i want to know what we will evolve into next and when please. i need to know by tomorrow

That’s not how it works.
Evolution is a slow process that takes millions of years. Nobody knows what will become of us.

The fact that we are over 95% alike to monkeys doesn’t mean we evolved from monkeys, it just means we have a common ancestor.

Evolution does not make schedules, it’s just based on adaptions that just happen to increase the chances of a species’ chances of survival, whatever we evolve into next depends on whatever environmental conditions we face. Also, we never evolved from any Dinosaurs. There were Mammals during the Age of Dinosaurs that were mostly small, Shrew-like animals, which in turn evolved from Mammal-like Reptiles that first evolved before the Dinosaurs did.

Your friends are misleading you. Maybe they’re actually lying to you – are you sure they’re really friends?

Humans are a mammals. Thy are descended from cynodonts, which evolved in the late Permian period. This is a totally different branch of the evolutionary tree to the archosaurs, which eventually evolved into dinosaurs (including T-Rex) and birds. They are both part of Phylum Chordata, however.

Evolution does not follow any set plan, so there’s no way to tell what humans will evolve into. We must wait and see. Check back here in 2 million years.

Wha? Nno, man, we not evolved from no T-Rex. We ape-men. We come from a long line o’ hairier, stupider ape-men who came from a bunch of even hairier, less-like-ape-men. Now, the current schedule is for us to evolve into more hairless even-less-like-ape-men as soon as Bush gets his way and we all get irradiated in a large nuclear apocalypse. After that, who knows?

we did NOT evolve from a t-rex. we evolved from small mammals living around the same time as the dinosaurs and after they died it opened up the evolutionary window for mammals to thrive. no one knows what we will evolve into next, that is the beauty of evolution

Perhaps yes, and we might become more human, intellectual, rational, logical and with better skills like the STAR TREK group. I am sure, we will learn to fly, swim, ride horses, and do stunts more easily. Our mental problem solving ablities too will be sharper.

This question makes me think you subscribe to the punctuated equilibrium view of evolution. Thanks, Gould (not).

Oh yeah and we didn’t evolve from t-rexs.

May 36th, 3428 – we turn into creatures with huge wings, tails, and gills.We gain the ability to live forever and raise the dead also! I can’t wait!:)

Learn from the other answerers here, then tell your friend he is stupid.

My friends told me that the oldest man (who already long dead) ever to have lived was a japanese man who lived to over 200 years old.

Is this true?

That Japanese Man was only 119.
A French Woman lived to be 122.

These are the oldest Man & Woman, in recorded history.

To correct a misconception, many ancient societies used the lunar month to tell time. The "Methuselah the oldest was 900 plus." is such an example. Converted to our calendar (13 lunar month per year, 900 months = 69 years) People in the Bible were "old" as the life expectancy was only 26 years.Further the Bible states "three score and ten" (70 years) as a man’s life expectancy

My grades are not great, so I am not interested in any really good schools. I’m looking at colleges like Hunter and College of Staten Island. Do those schools or any others have good anthropology programs?

CUNY

What do you mean "like Hunter". What’s wrong with Hunter ? I majored in Anthro at the 68th St campus and the Graduate Center has Masters programs in planning and anthro.

NYU is good if you can get in and can afford it.

Look at the main website for CUNY to find other campuses that offer Anthro.
