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?


What is an example of a heterozygous genotype?


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.
