The northern and Mexican spotted owls are an example of:

  1. Sympatric speciation
  2. Convergent evolution
  3. Gene flow between owls
  4. Allopatric speciation
Show answer and solution

Correct answer: D. Allopatric speciation

1. They live in geographically separate places. 2. This is allopatric speciation. 3. Different climates drive different adaptations. _Source: OpenStax Biology 2e, Chapter 18, Evolution and the Origin of Species (CC BY 4.0)._

The integration of genetics and evolution that took shape by the 1940s is called the:

  1. Modern synthesis
  2. Blending theory
  3. Founder effect
  4. Hardy-Weinberg law
Show answer and solution

Correct answer: A. Modern synthesis

1. It links natural selection to genetic makeup. 2. This is the modern synthesis. 3. It is generally accepted today. _Source: OpenStax Biology 2e, Chapter 19, The Evolution of Populations (CC BY 4.0)._

Population change over time within a species is called:

  1. Extinction
  2. Microevolution
  3. Macroevolution
  4. Speciation
Show answer and solution

Correct answer: B. Microevolution

1. It is change in allele frequencies. 2. That is microevolution. 3. New species and higher groups are macroevolution. _Source: OpenStax Biology 2e, Chapter 19, The Evolution of Populations (CC BY 4.0)._
