Adaptation

The process by which a species becomes better suited to its environment over time.

Natural selection

The mechanism by which individuals with advantageous traits for survival and reproduction are more likely to pass on their genes to the next generation.

Trait

Genotype

The genetic makeup of an organism.

Phenotype

The observable physical or biochemical characteristics of an organism, determined by its genotype and environmental factors.

Evolution

The process of change in species over time, driven by mechanisms such as natural selection and genetic drift.

Allele

Different forms of a gene that can occupy a specific location on a chromosome.

Mutation

A change in the DNA sequence of an organism, which can lead to new traits.

Cladogram

A diagram showing the evolutionary relationships between a group of species.

Genetically Modified Organism (GMO)

An organism whose genetic material has been altered using genetic engineering techniques.

Fitness

The ability of an organism to survive and reproduce in its environment.

Gene

A unit of heredity that is passed from parent to offspring and determines some characteristic of the offspring.
