| 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. |
