part 3 Flashcards
he mutual, interactive evolution of human biology and culture; the concept that biology makes culture possible and that developing culture further influences the direction of biological evolution; a basic concept in understanding the unique components of human evolution. (Jurmain et al. 2012: 7)
biocultural evolution
is the area of evolutionary biology that studies how social interactions, especially between individuals of the same species, arise, change and are maintained. A particular focus is on how cooperative behaviour can be beneficial despite the intuitive advantages of being selfish.
social evolution
is any human-like species (Manlike Primates), who is Bipedal (walks on two legs) and is intelligent (has a large brain and uses tools). The development of the different species of primates which were able to evolve in 40 million years ago.
hominid
This hominid believed to have lived 14 million years whose remains could be found in Siwalik Hills of India. The description of this hominid could stand upright and used stones and sticks to frighten his enemies. This kind of species was found by Mrs. Mary Leaky at the volcanic ash of Laetolil, Tanzania, East Africa in 1975.
“Ramapithecus”
The American archeologist, Donald C. Johanson discovered a whole skeleton of a teenage girl at Hadar, Addis Ababa, Ethiopa.
lucy
was believed o lived in Africa about 5 million years ago. He had small brain but could walk straight and used simple tools
“Australopithecus”
traits of hominid
bipedalism and big brains.
b.The brain case, or the skull, has increased in size over time.
c.The skull now has more forehead and a rounder shape.
d.There is less separation between the brain and the face.
e.Big brains allow for more learned behavior, such as using tools. All hominids are able to walk upright.
f.The femur, which is the thigh bone in hominids, is angled towards the knee, which stabilizes the body in relation to gravity.
diet of hominid
Hominids started out as herbivores, eating mostly coarse, tough food that needed a lot of chewing. As the diet began to include small animals and cooked food, the teeth and jaws became smaller and smaller over time.
✗By the time Neanderthal man came on the scene, hominids had become omnivores, eating a variety of foods, such as fruit, leaves, seeds, nuts, grains and meat.
✗The Neanderthals introduced cooking. Eating cooked foods does not require the large teeth and jaws to chew.
There are four general areas of behavior that are common to hominids. These are:
• The ability to use tools
• Social dynamics
• Capability for language
• Aggression
behavior
Lived from 2.33 to 1.44 million years ago, is called the handy man by anthropologists due to their use of tools particularly stone flakes to use as weapons and protection of their enemies.
homo habilis “handy man”
the Physical description of this species was about 4 feet and could walked upright with small brain. He used crude stone weapons for protections against predators. This was discovered by Dr. Louis S. B. Laekey (Husband of Mrs. Mary Leakey) in Olduva George, Tanzania, East Africa in 1999 which believed to live about 1.75 million years ago.
“Zinjanthropus”
This species was about 5 feet tall and walked upright. He used more refined stone tools with brain double size of chimpanzee’s brain. This was excavated in Lake Turkana, Kenya, East Africa by Dr. Richard Leakey (the son of the famous Dr. and Mrs. Leakey)
lake turkana
Lived from 1.9 million to 143,000 years ago, used tools extensively as well as fire. There is some evidence that homo erectus built rafts to travel over water. Anthropologists don’t know if homo erectus cooked its food, although we do know that it ate meat.
homo erectus “upright man”
This was discovered by Eugene Dubois at Trinil, Java, Indonesia in 1891 which was the called the “Java Man.” The physical characteristics of this homo erectus were about 5 feet tall; could walk eredt; heavy and chinless jaw; hairy body of modern man.
“Pithecanthropus Erectus” (“Java Man”)
This homo erectus species was discovered at Choukoutien village, Beijing, China in 1929. This was about 5’2” tall, could walk upright, and the brain almost as large as the modern man which was believed to lived 500,000 years ago.
Sinanthropus Pekinensis” (“Peking Man”)
