Evolution (NGSS)

Front

This type of evolution happens on a small scale, typically within a single population.

Back

microevolution

Front

large-scale evolutionary change that takes place over long periods of time

Back

macroevolution

Front

Body parts in different organisms that have the same basic structure, but may have different functions.

Back

homologous structures

Front

Body parts in organisms that have the same functions, but have different structures

Back

Analagous structures

Front

Body parts found in living organisms that no longer serve a purpose (not necessary for the organism's survival).

Back

Vestigial structures

Front

Selective pressure exerted by humans on populations in order to improve or modify particular desirable traits.

Back

Artificial selection

Front

The process by which characteristics of a population change over many generations as organisms with heritable traits survive and reproduce, passing their traits to offspring.

Back

natural selection

Front

A change in a population or species over time

Back

Evolution

Front

Organisms descended from a common ancestor. Organisms with a more recent common ancestor are more closely related. This phenomenon is referred to as?

Back

Common Ancestry

Front

Two organisms that are closely related would have...
Options:
1. very similar DNA sequences
2. no proteins in common
3. exactly the same DNA sequences
4. completely different DNA sequences
