Lesson 1 (Q2) Flashcards
The origin and development of modern humans can be explained through study of
biological and cultural evolution
are key concepts in the study of the origins of modern humans.
Biological and cultural Evolution
refers to the charges, modifications, & variations in the genetics and inherited traits of biological populations.
Biological Evolution
Refers to the changes or development in cultures from a simple form to a more complex form of human culture.
cultural/sociocultural Evolution
A result of human adaptation to different factors like climatic changes and population increase
cultural/sociocultural Evolution
Biological evolution is based on the theory that was introduced by the famous English naturalist and geologist.
charles darwin
Because of the result of Charles Darwin’s studies, he introduced the concept of evolution to explain the origins of modern humans in his published work entitled
On The Origins of species by Means of natural selection (1859)
Natural selection has 3 important principles
1 Variation
2 Heritability
3. Differential reproductive success
-organisms exhibit individual variation in appearance and behavior
Variation
- traits are consistently passed from parents to offspring.
Heritability
- leave mort offspring in the next generation
Differential reproductive success
The transformation from apelike ancestors to modern humans occured after million yrs of
biological & cultural evolution
In this process of evolution, our apelike ancestors developed and eventually became modern humans
biological & cultural evolution
For archeologist, these are important sources of information in the recontruction of human evolution.
artifacts and fossils
refer to human, plant, and animals remains to have preserved through time
Fossils
refers to the objects that were made and used by humans.
Artifacts
General term used by the scientist to categorize the group of early humans and other human- like creatures that can walk erect during the prehistoric times.
Hominid
4 categories of hominid based on the age of artifacts and fossils that were found.
Sahelanthropus, Ardipethecus, Australopithecus, and Homo
-they are considered as the prehuman stage of evolution.
The Australopithecus, Sahelanthropus and Ardipethecus
is part of the human stage of evolution
Homo
Their Fossils were all excavated in the African continent
Australopithecus, Sahelanthropus and Ardipethecus
The first hominid came from the lineage of
Sahelanthropus tchadensis species (6-7 million ago yrs
