Evolution Review

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. It is a key mechanism of evolution.

Front

What is Divergent Evolution?

Back

Divergent Evolution occurs when two or more related species become more dissimilar over time, often due to different environmental pressures.

Front

What does a common ancestor indicate?

Back

A common ancestor indicates that two species share a lineage and have evolved from the same ancestral species.

Front

What are the traits of conifers?

Back

Conifers have vascular tissue and seeds, but they do not produce flowers.

Front

What is the Founder Effect?

Back

The Founder Effect is a genetic phenomenon that occurs when a small group of individuals establishes a new population, leading to reduced genetic diversity.

Front

What is the Bottleneck Effect?

Back

The 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 Coevolution?

Back

Coevolution is the process where two or more species influence each other's evolution, often seen in predator-prey relationships.

Front

What is the significance of DNA similarity in species?

Back

Similar DNA between species suggests that they are closely related and likely share a common ancestor.

Front

What is the role of mutations in evolution?

Back

Mutations are changes in DNA that can lead to new traits in organisms, providing raw material for natural selection.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a variety of forms to adapt to different environments.
