Evolution
Three parts of evolution
Variation
Adaptation
Inheritance
Biological similarities and differences originated at the creation, characteristics of life forms were seen as immutable.
Creationism
After each destructive event, god was created again, leading to contemporary species
Catastrophism
- Father of Geology
- he defines the uniformitarianism
Charles Lyell
States that the present is the key to the past. Explanations for past events should be sought in the long term action of ordinary forces that still operate today.
uniformitarianism
- Compared with contemporary humans, they had very small brains.
- Their trait that has been lost during subsequent human evolutions big back teeth.
Early Hominins
The earliest widely accepted hominin genus. (5.8-4.4 million years ago)
Ardipithecus
Adaptation to open grassland or savanna
Bipedalism
She was one of the first hominin fossils to become a household name. Her skeleton is around 40% complete - at the time of her discovery, she was by far the most complete early hominin known.
Lucy: Australopithecus Afarensis
- Team led by scientists Louis and Mary Leakey uncovered the fossilized remains of a unique early human between 1960 and 1963 at Olduvai Gorge in Tanzania.
- The word habilis is based on a Latin word meaning ‘handy’ or ‘skilful’. This species is known as ‘handyman’ because stone tools were found near its fossil remains and it is assumed this species had developed the ability to modify stone into tools.
Homo Habilis
The extinct ancient human _____ is a species of firsts. It was the first of our relatives to have human-like body proportions, with shorter arms and longer legs relative to its torso. It was also the first known hominin to migrate out of Africa, and possibly the first to cook food.
Homo Erectus
found 1964 near lake Turkan, Kenya. This is the most complete homo erectus ever found.
Nariokotome Boy
The earliest members of our species, along with the neanderthals of Europe and the middle east.
Neanderthal (H. Sapiens Neanderthalensis)
The stone tool techniques evolved out of the oldowan or pebble tool tradition that lasted 15,000 years ago.
Paleolithic
The final stage of technological development among prehistoric humans.
Neolithic
