A change/alteration to DNA that can be caused by environmental factors
Advantageous variations which help organisms survive in their environments
The ongoing process of change in the inherited features of a population of organisms over time.
The process by which organisms with variations better adapted to their environments are more likely to survive, reproduce, and pass along their traits to offspring..
Differences in traits among individuals of the same species.
Organisms must fight for resources such as food, space, or a mate.
When populations have adaptations that help them to survive in their environment, they will increase in number.
Although food, water, and space in some environments may be abundant, there is always more offspring than available resources.
Different species often have similar structural characteristics, or display molecular similarities in their DNA/proteins
Changes in the environment that force species to adapt/change
The elimination of an entire population or species that is unable to adapt to changes in the environment
A diagram that shows how different species are related and have changed over time.
