Which characteristic separated hominids from apes?

Question

larger body

larger teeth

larger eyes and ears

larger brain

A(n) ____________________ is any variation that makes an organism better suited to its environment.

Answer 1

s*x organs

Answer 2

I agree that the question is not that good because the distinction between hominid and ape  is largely non existent. The answer they are looking for is larger brain.  An adaptation is how I would answer the second one but I am not too sure.

Answer 3

I don't understand the last part of the question (maybe evolutionary advantage???).

At any rate the answer is brains.  The jaw is much smaller on hominids so it is not teeth - eyes and ears are irrelevant....

Now that I think about it - this question is retarded becuase which apes are you refering to? Orangutans?  Gorillas? Some sort of ancient ape that is now extinct?

There is no answer to this question.

Answer 4

Hominids are apes adapted to living in open savanna or broken woodlands, as opposed to all other apes, which live in forest/jungle.

As a result, hominids:

Locomoted bipedally

Had relatively larger, teeth, with thicker enamel, in order to eat the harder foods in the open environment.

One group of hominids, started scavenging meat, and using tools to a greater extent than the others, and this is the group that led to humans.

Answer 5

By definition a Hominid is, taxonomically, a member of the Hominidae family. This family includes all great apes: Gorilla, Chimpanzee, Orangs, Humans.

The primatological term is easily confused with a number of very similar words:

A hominoid is a member of the superfamily Hominoidea: extant members are the lesser apes (gibbons) and great apes.

A hominid is a member of the family Hominidae: all of the great apes.

A hominine is a member of the subfamily Homininae: gorillas, chimpanzees, humans (excludes orangutans).

A hominin is a member of the tribe Hominini: chimpanzees and humans.

A hominan is a member of the sub-tribe Hominina: modern humans and their extinct relatives.

A human is a member of Homo sapiens and is sometimes also used to refer to any extinct member of the genus Homo or members from other hominan genera.

A humanoid is a vaguely human-shaped entity; the term is typically used in fiction.

Edit after a few hours...

Assuming the questioner is a bit confused and is looking for the characteristic that separated humans or hominans from the other great apes, the answer is none of the above. The distinguishing characteristic is in the mechanics of the knee:

The human knee allow for a small amount of rotation on full extention. They also have an inward angle (slightly knock-kneed, this is called a Q angle) This allows the knee to lock and muscles to relax when standing, and allows for a smoother transition of energy from in front to behind when walking.

Put simply, in means we are proper bipeds. Chimps, by contrast can neither fully straighten their knees, nor keep their bodies upright when they 'walk'. This means they waddle from side to side, and tend to the locomotion of knuckle dragging.

The knee mechanics led to the repositioning of the Skull, Lumbar Spine, and pelvis, which allowed for far larger heads to pass through the birth canal, and so for larger brains. At the same time the forelimbs are freed from the burden of weight bearing and are able to become manipulative limbs to make increasingly more delicate use of tools with the intelligence the brian bestows.

So the answer is "The Knee".

An (evolutionary) advantage is any variation that makes an organism better suited to its environment.
