Key Concepts

Extinction

Extinction is the process by which a species ceases to exist, typically because of an inability to adapt to changing environmental conditions, competition, or catastrophic events. It marks the end of a species' evolutionary lineage.

Adaptive Radiation

Adaptive radiation occurs when a single ancestral species rapidly diversifies into a multitude of new forms that occupy different ecological niches. This burst of divergence happens when environmental changes create opportunities for species to explore new resources or habitats.

Cladogram

A cladogram is a branching diagram used to illustrate the evolutionary relationships among species. It represents nested sets of shared characteristics and depicts a hypothesis of the patterns of ancestry and descent, showing how species diverged from common ancestors over time.

Sexual Selection

Sexual selection is a form of natural selection where individuals with traits that are advantageous in competing for mates have a greater likelihood of reproducing. These traits, which may not necessarily improve survival, enhance reproductive success in the context of mate acquisition.

Coevolution

Coevolution refers to the process where two or more species reciprocally influence each other's evolution. This interaction can lead to the development of interdependent traits or relationships, as the species adapt in response to the pressures exerted by one another, often seen in predator-prey systems or mutualistic partnerships.

Gene Flow

Gene flow is the transfer of genetic material between separate populations. Alleles enter and leave populations as individuals migrate, thus promoting genetic diversity and sometimes reducing differences between populations over time.

Phylogeny

Phylogeny is the study of the evolutionary history and relationships among species or groups of species. It often involves reconstructing ancestral relationships and evolutionary paths to understand how current organisms have diversified from common ancestors.

Genetic Drift

Genetic drift is the change in the frequency of alleles within a population due to random chance events. Unlike natural selection, the alleles are altered not because of adaptive value but by random fluctuations, which can have significant effects especially in small populations.
