The first really human-like hoinids appeared |
around 2.5-1.8 mya. These hominds are all |
given the genus (group) name Homo, and |
include us. |
|
The best known examples are Homo |
Australopiths and Homo Habilis. |
|
The first early humans were taller than |
australopiths and had bigger brains. |
|
Unlike australopiths, these hominids ate |
meat. They may have been forced to eat |
meat when the climate warmed up, cutting |
the amount of plant food that was available. |
|
Brains need a lot of food, and eating meat |
gave the extra nourishment that is required |
for bigger brains. |
|
Homo hibilis is known from pieces of hand |
bones, a jay and a skull found in Tanzania's |
Olduvai Gorge in 1961. |
|
Homo habilis means 'Handy Man'. He get his |
name because he has a good frip for wielding |
tools- with a thumb that can be rotated to |
meet the tip of a finger. This is called an |
opposable thumb'. |
|
The first homo species used stones to break |
open bones for the nourishing marrow |
inside. Later sharpened stones to cut meat |
for eating and hides for maing clothing. |
Experts believe that they may even have |
built simple shelters to live in. |
|
Some experts think the bulge in 'Broca's |
area' of some Homo habilis skulls suggest |
that they could speak in a crude way. Most |
think they could not. |
|
The first hominids in the genus Homo lived |
for a million or more years alongside |
robust' (bigger) australopiths such as |
Paranthropus boisei. |
