Bio Unit 8 Principles of Evolution

Evidence sources for Darwin's theory of evolution are

Refers to the situation that occurs when the high number of offspring results in a competition for resources. 

A measure of the ability to survive and produce more offspring relative to other members of the population.

Traces of organisms that lived in the past

Structures that perform similar functions but are not similar in origin. 

The process by which humans decide which of an organism's traits are most desirable

Features that are similar in structure but appear in different organisms and have different functions.

The Swedish botanist that developed the classification systems for all types of organisms

Did not believe species could change and developed a theory known as catastrophism.

A group of organisms that are closely related and can reproduce fertile offspring.

A French naturalist who proposed that all organisms evolved toward perfection.

The process by which traits are passed on because they increase survival and reproduction rates

The type of evidence that best supports Darwin’s ideas on descent with modification

The 4 main principles of Darwin's theory of natural selection are

The theory that states that natural disasters shaped landforms and caused species to become extinct.

A feature that allows an organism to better survive and reproduce in its environment

The difference in the physical traits of an individual from those of others in the population

Slow processes that happened in the past over long periods of time were responsible for changes in landforms.

All the individuals of a species that live in an area

Remnants of organs/structures found in early ancestors that no longer serve a useful function.
