What is Differential Fitness?

Back

Differential Fitness refers to the variation in the ability of individuals within a population to survive and reproduce based on their phenotypic traits.

Front

What are the Galapagos Islands known for?

Back

The Galapagos Islands are known for their unique biodiversity and as the location where Charles Darwin observed species that contributed to his theory of evolution.

Front

What is Stabilizing Selection?

Back

Stabilizing Selection is a type of natural selection that favors intermediate variants of a trait, reducing variation and selecting against extreme phenotypes.

Front

What is a Bottleneck Effect?

Back

A Bottleneck Effect occurs when a population's size is significantly reduced for at least one generation, leading to a loss of genetic diversity.

Front

What is Natural Selection?

Back

Natural Selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is Directional Selection?

Back

Directional Selection is a mode of natural selection in which one extreme phenotype is favored over others, causing a shift in the population's trait distribution.

Front

What is Disruptive Selection?

Back

Disruptive Selection is a type of natural selection that favors extreme phenotypes at both ends of the spectrum, leading to increased variation.

Front

What is Genetic Drift?

Back

Genetic Drift is a mechanism of evolution that refers to random changes in allele frequencies in a population, often having a more significant effect in small populations.

Front

What is the Founder Effect?

Back

The Founder Effect occurs when a small group of individuals establishes a new population, leading to reduced genetic variation compared to the original population.

Front

What is Speciation?

Back

Speciation is the evolutionary process by which populations evolve to become distinct species.
