|
What is scientific theory? |
A coherent explanation made up of many supported hypothesis. |
Show proof what |
|
|
What is Jean-Baptiste Lamarck’s theory of evolution? |
Evolution occurred through the inheritance of traits that individuals acquired through their lifetime. |
Inherited traits |
|
|
Anthropology is the study of what? |
Humans |
|
|
|
What is an example of a heterozygous genotype? |
Aa |
One big letter/one small |
|
|
What are the four forces/process of evolution? |
Genetic Drift, Gene Flow, Mutation and natural selection |
|
|
|
What is evolution? |
Change in frequencies of alleles from one generation to next. (Change in time of genetic makeup) |
|
|
|
What are the four fields of anthropology? |
Cultural anthropology, archaeology, linguistics anthropology, and physical/biological anthropology. |
C + A + L + P/B |
|
|
What is the scientific method? |
A body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. |
|
|
|
What is Archaeology? |
The study of past societies and their cultures, especially of the past, such as tools, food remains and places where people lived. |
|
|
|
What is Linguistic Anthropology? |
The study of language, especially how language is structured, the evolution of language, and the social and cultural context for language. |
|
|
|
What is Physical/Biological Anthropology? |
The study of human evolution and variation, both past and present. |
|
|
|
What are hominins? |
Humans and human like ancestors. |
|
|
|
Define Genome? |
The complete set of genetic information- chromosomal and mitochondrial DNA- for an organism or species that represents all of the inheritable traits. |
|
|
|
What are the six big events of human evolution? |
1. Bipedalism 2. non-honing chewing 3. Dependence on material culture 4. speech 5. hunting 6. domestication of plants and animals. |
|
|
|
What is a hypothesis? |
Testable statement that potentially explain specific phenomena observed in the natural world. |
|
|
|
What is Darwin’s hypothesis of the origin of human bipedalism? |
A link in the shift from life in the trees to life on the ground. |
|
|
|
What is scientific law? |
A statement of fact describing a natural phenomena. |
|
|
|
What are species? |
A group of related organisms that can interbreed and produce fertile, viable, offspring. |
|
|
|
What is natural selection? |
The process by which some organisms, with features that enable them to adapt to the environment, preferentially survive and reproduce, thereby increasing the frequency of those features in the population. |
|
|
|
What are Darwin’s three postulates theory? |
The ability of a population to expand is infinite, while the resources available to sustain said population are finite. This dynamic causes a struggle for existence among individuals as they compete for resources. Organisms vary in their physical qualities; these variations allow some members to reproduce more successfully than others. These variations are inherited by offspring from their parents. |
|
|
|
Who rediscovered Hutton’s work and the idea of uniformitarianism? |
Charles Lyell |
|
|
|
What is uniformitarianism? |
The theory that processes that occurred in the geologic past are still at work today. |
|
|
|
What was Thomas Malthus’ contribution to science? |
Founded demography: only some will find enough food to survive. |
|
|
|
What is Catastrophism? |
the theory that changes in the earth's crust during geological history have resulted chiefly from sudden violent and unusual events. |
|
|
|
What are Mendel’s basic discoveries of inheritance? |
1. Inheritance is particulate: traits are determined by two unseen particles (genes/alleles) you receive from your parents. 2. Principal of segregation: when gametes are formed, the gamete receives one of these genes (via a chromosome) randomly. 3. Genes can have different alleles, they can be dominant or recessive. |
|
|
|
What is a genotype? |
Genetic makeup; combination of alleles. |
|
|
|
What are Phenotypes? |
Physical characteristics of an organism; the expression of genotype. |
