world. Homo sapiens‚ or humans‚ first popped up around 500‚000 years ago‚ were found globally‚ and showed tendencies of modern human culture (04/19 lecture). Neandertal remains have been dated back to 1000‚000 years ago‚ were found Eurasia in more extreme cold climates and showed tendencies of modern humans‚ such as having a material culture. These two “species” interbreed with each other. The biological species concept classifies species

Summary: Humans‚ apes and monkeys share a common ancestor. This ancestor lived about 45 million years ago. Many fossils have been found traits of both humans and apes; also comparisons of modern humans and apes support this theory. PRIMATES Primates are a group of mammals that have special characteristics that include: both eyes are located at the front of the head and they provide binocular or three-dimensional vision; also all primates have 5 fingers (four fingers and a thumb). The ancestors

We know what we know about history from the examining of fossils‚ DNA records‚ ‚ and technological advances overtime. Spearheaded by the Germans discovery of the skullcap and limbs‚ archaeologists gather information‚ make inferences‚ and use their imaginations to construct how things use to be. The conditions of the fossils let us know the kinds of conditions people/animals lived in. This can be problematic because for example‚ Neanderthal bones and deer bones were mixed together with some of the

two theories that scientists have come up with over the years to explain the theory of evolution were the multiregional theory and out of Africa theory. The multiregional theory expresses the idea that Homo erectus developed in different parts of the world. The out of Africa theory expresses that Homo erectus developed in Africa nearly two million-years-ago and as the temperatures changed‚ they moved throughout the world and developed differently. “The multiregional view posits that genes from all

”Out of Africa Theory” The Out of Africa Theory is a widely renown theory describing the origin of the human race and their early dispersal throughout the world. According to this theory‚ humans have a monogensis‚ or a single and common origin; Africa. The concept was first introduced in 1871 by Charles Darwin but was deliberated for years until further studies of mitochondrial DNA and evidence ”based on physical anthropology of archaic specimens” was added. During the early 19th century‚ scientists

Saving energy was applied to having and raising more offspring. Homo habilis‚ meaning handy man‚ is the same as the Australopith but they have little different physical characteristics. Homo habilis have bigger brains‚ less hair‚ and have a flat nose not as flat. They also don’t have a leathery face. Homo habilis began to observe the environment for clues to food. They developed more teamwork and scared away predators. Homo habilis had stone tools called

Language assisted in making us truly ‘human’ in a variety of different ways‚ however it is through the main factors of the extent of the efficiency of our unique method of communication‚ enabling the ability to share unlimited knowledge with one another and finally‚ the role it played in accommodating humans with the ability to adapt to foreign environments. It is through these three key features that language is distinctly outlined as being a main influence on the characteristics of typical human
