Evolution and Biological Adaptation

1,354 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 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

How has horror evolved over time to reflect changing societal values and beliefs?

  1. Horror has become less graphic and violent

  2. Horror has become more psychological and introspective

  3. Horror has become more diverse and inclusive

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

Horror has undergone significant evolution, becoming less graphic, more psychological, and more diverse.

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.

  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. The gene-culture coevolution theory

  2. The dual inheritance theory

  3. The cultural evolutionary theory

  4. The cultural materialism theory

A Correct answer
Explanation

The gene-culture coevolution theory is the idea that culture is a product of the interaction between biology and the environment.

Multiple choice

Which theory is widely accepted to explain the origin of life on Earth?

  1. Abiogenesis

  2. Intelligent Design

  3. Panspermia

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

Abiogenesis is the prevailing scientific theory that proposes that life arose from non-living matter through a series of chemical reactions under suitable conditions.

Multiple choice

What is the term used to describe the process by which organisms adapt to changes in their environment?

  1. Adaptation

  2. Acclimatization

  3. Evolution

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

Adaptation is the process by which organisms acquire traits that make them better suited to their environment, increasing their chances of survival and reproduction.

Multiple choice

Which evolutionary theory proposes that individuals select mates who possess traits that increase the survival and reproductive success of their offspring?

  1. Natural Selection

  2. Sexual Selection

  3. Kin Selection

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

Natural selection is the process by which individuals with traits that are better suited to their environment are more likely to survive and reproduce, passing those traits on to their offspring.

Multiple choice

Which evolutionary theory suggests that individuals select mates who possess traits that indicate good genes or genetic fitness?

  1. Good Genes Hypothesis

  2. Fisherian Runaway Selection

  3. Parental Investment Theory

  4. Mate Choice Copying
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The good genes hypothesis proposes that individuals select mates who possess traits that indicate good genes, such as physical attractiveness, symmetry, and health, as these traits are likely to be passed on to their offspring.
