Evolution and Biological Adaptation

1,288 Questions

Evolution and biological adaptation focus on natural selection, speciation events, and how organisms adjust to environmental changes over time. These foundational biology concepts appear frequently in general science sections of civil services and school board examinations. Use these questions to study evolutionary theories, ancestral traits, and the fossil record.

Evolution and Biological Adaptation Questions

Multiple choice

Which of the following is a key concept in evolutionary psychology of aging?

  1. Life history theory

  2. Natural selection

  3. Sexual selection

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Life history theory, natural selection, and sexual selection are all key concepts in evolutionary psychology of aging. Life history theory focuses on how organisms allocate resources to growth, reproduction, and survival. Natural selection favors traits that increase an organism's chances of survival and reproduction. Sexual selection favors traits that make an organism more attractive to potential mates.

Multiple choice

Which of the following is an example of natural selection in aging?

  1. Humans who live longer are more likely to have children

  2. Humans who live longer are more likely to be healthy

  3. Humans who live longer are more likely to be wealthy

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural selection in aging favors traits that increase an organism's chances of survival and reproduction. Humans who live longer are more likely to have children, be healthy, and be wealthy. All of these factors increase an individual's chances of passing on their genes to the next generation.

Multiple choice

Which of the following is an example of sexual selection in aging?

  1. Men who are older are more likely to be attractive to women

  2. Women who are older are more likely to be attractive to men

  3. Older people are more likely to be attractive to younger people

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

There is no evidence that older people are more attractive to potential mates. In fact, most studies have found that younger people are more attractive to potential mates.

Multiple choice

What is the evolutionary perspective on aging?

  1. Aging is a process of decline.

  2. Aging is a process of adaptation.

  3. Aging is a process of both decline and adaptation.

  4. Aging is a process that is not well understood.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The evolutionary perspective on aging is that it is a process of both decline and adaptation. On the one hand, aging is associated with a decline in physical and cognitive function. On the other hand, aging is also associated with an increase in wisdom and experience. These changes are thought to be the result of natural selection, which favors traits that increase an organism's chances of survival and reproduction.

Multiple choice

What is the term used to describe the process by which life may have originated from non-living matter?

  1. Abiogenesis

  2. Biogenesis

  3. Photosynthesis

  4. Cellular Respiration
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Abiogenesis is the process by which life may have originated from non-living matter. It is a complex and poorly understood process, but scientists believe that it may have occurred in hydrothermal vents or other environments on early Earth.

Multiple choice

What is the term for the process by which a community of organisms changes over time?

  1. Ecological Succession

  2. Evolution

  3. Adaptation

  4. Migration
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ecological succession is the process by which a community of organisms changes over time, as new species enter and others leave.

Multiple choice

What is the term for the process by which species adapt to changes in their environment?

  1. Evolution

  2. Adaptation

  3. Natural selection

  4. Genetic drift
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Adaptation is the term for the process by which species adapt to changes in their environment, allowing them to survive and reproduce in new conditions.

Multiple choice

What is the term for the process by which species evolve to become more resistant to pesticides or antibiotics?

  1. Resistance

  2. Adaptation

  3. Evolution

  4. Natural selection
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Resistance is the term for the process by which species evolve to become more resistant to pesticides or antibiotics, making it more difficult to control pests or diseases.

Multiple choice

The idea that culture is a product of natural selection is known as:

  1. The cultural evolutionary theory

  2. The gene-culture coevolution theory

  3. The dual inheritance theory

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The cultural evolutionary theory, the gene-culture coevolution theory, and the dual inheritance theory are all theories that propose that culture is a product of natural selection.

Multiple choice

  1. Acclimatization

  2. Adaptation

  3. Evolution

  4. Photosynthesis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Acclimatization is the process by which plants respond to changes in their environment, such as changes in temperature, light intensity, or water availability.
