Key Concepts

Sedimentary Rock

A type of rock formed from the accumulation and lithification of sediment. It is significant in geology for its ability to contain fossils and record past environmental and climatic conditions.

Homologous Structures

Anatomical features in different species that originate from a common ancestor, even though they may now serve different functions. They provide evidence for divergent evolution and shared evolutionary history.

Analogous Structures

Structures in different species that perform similar functions but are not derived from a common ancestral feature. They illustrate convergent evolution, where similar environmental pressures lead to similar adaptations in unrelated organisms.

Half-Life

A term used in radiometric dating referring to the time required for half of the radioactive isotopes in a sample to decay. It is essential in determining the age of rocks and fossils.

Neutral Mutation

A genetic mutation that does not affect an organism's fitness. It can accumulate over time and contribute to genetic variation without influencing natural selection directly.

Natural Selection

A fundamental mechanism of evolution where traits that enhance survival and reproduction become more common in successive generations. It explains how populations adapt to their environments over time.

Fossils

Remains, traces, or imprints of ancient organisms preserved in geological formations. Fossils provide critical evidence about the history of life, evolutionary processes, and past environmental conditions.

Fitness

A concept in evolutionary biology that refers to the reproductive success of an individual or genotype. It measures how well an organism passes its genes on to the next generation compared to others in the population.

Homeotic Genes

Genes that regulate the development of anatomical structures in organisms. They play a key role in determining the identity and arrangement of body parts during embryonic development.
