A fast increase in the number of cells or organisms, like when cells multiply during growth or healing.

The shape and structure of an organism or its parts, like the wings of a bird or the leaves of a plant.

How the parts of a living thing work, like how the heart pumps blood or how lungs help us breathe.

A trait or behavior that helps an organism survive better in its environment, like thick fur in cold climates.

The process where organisms with traits that help them survive are more likely to live and have offspring, passing those helpful traits on.

the process by which living things slowly change over time. These changes can help them survive better in their environment.

the series of stages a living thing goes through from birth to adulthood and then to reproduction.

living thing can reproduce without needing a partner. The offspring are usually exact copies of the parent.

reproduction that involves two parents. The offspring get a mix of traits from both parents.

Environmental factors

things in the surroundings, like temperature, food, or sunlight, that can affect how a living thing grows and survives.

a helpful difference in a living thing that makes it more likely to survive or reproduce in its environment.

Evolution by Natural Selection (survival of the fittest)

the mechanism by which species become ideally suited for their environment

Descent with Modification (Tree of Life)

Includes the Unity of Life (what we have in common) and Diversity of Life (what makes different)

a group of organisms who can breed together and create fertile offspring

individuals of the same species that breed together and live in the same area.

phenotypic change in species over a period of time

different genotypes (alleles) for a trait, can result in different phenotypes in an individual

natural selection (survival of the fittest)

the environment determines which organisms survive to pass on their genes to the next generation

inheritable trait that allows for survival in an environment, can be structural or chemical or behavioral

Process of Natural Selection

Term	Definition
proliferation	A fast increase in the number of cells or organisms, like when cells multiply during growth or healing.
morphology	The shape and structure of an organism or its parts, like the wings of a bird or the leaves of a plant.
physiology	How the parts of a living thing work, like how the heart pumps blood or how lungs help us breathe.
adaptation	A trait or behavior that helps an organism survive better in its environment, like thick fur in cold climates.
Natural selection	The process where organisms with traits that help them survive are more likely to live and have offspring, passing those helpful traits on.
Evolution	the process by which living things slowly change over time. These changes can help them survive better in their environment.
life cycle	the series of stages a living thing goes through from birth to adulthood and then to reproduction.
Asexual	living thing can reproduce without needing a partner. The offspring are usually exact copies of the parent.
Sexual	reproduction that involves two parents. The offspring get a mix of traits from both parents.
Environmental factors	things in the surroundings, like temperature, food, or sunlight, that can affect how a living thing grows and survives.
Beneficial variation	a helpful difference in a living thing that makes it more likely to survive or reproduce in its environment.
Evolution by Natural Selection (survival of the fittest)	the mechanism by which species become ideally suited for their environment
