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.

Multiple choice

What is the central question in the Problem of Biological Function?

  1. What is the purpose or function of a biological entity?

  2. How do biological entities function?

  3. Why do biological entities function the way they do?

  4. What is the evolutionary history of biological function?
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Problem of Biological Function is concerned with the purpose or function of biological entities, rather than how they function, why they function the way they do, or their evolutionary history.

Multiple choice

What is the mechanistic approach to explaining biological function?

  1. Biological functions are the result of natural selection.

  2. Biological functions are the result of chance events.

  3. Biological functions are the result of a vital force.

  4. Biological functions are the result of a divine plan.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The mechanistic approach to explaining biological function is based on the idea that biological functions are the result of natural selection. Natural selection is a process by which organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their genes to the next generation.

Multiple choice

What is the evolutionary function of a biological trait?

  1. The trait helps the organism survive and reproduce in its environment.

  2. The trait is a result of random genetic drift.

  3. The trait is a result of a mutation.

  4. The trait is a result of natural selection.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The evolutionary function of a biological trait is to help the organism survive and reproduce in its environment. Traits that are beneficial to an organism's survival and reproduction are more likely to be passed on to the next generation, while traits that are harmful are less likely to be passed on.

Multiple choice

What is the term used to describe the process by which marine organisms adapt to their specific environment?

  1. Adaptation

  2. Evolution

  3. Natural Selection

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

Adaptation refers to the process by which marine organisms develop traits and characteristics that enable them to survive and thrive in their specific marine environment.

Multiple choice

What was the name of the debate between Charles Darwin and Richard Owen about the theory of evolution?

  1. The Great Debate

  2. The Darwin-Owen Debate

  3. The Evolution-Creationism Debate

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

The Great Debate was a series of public debates between Charles Darwin and Richard Owen in 1860. The debates were held in Oxford, England, and were attended by a large audience. Darwin argued in favor of his theory of evolution by natural selection, while Owen argued against it.

Multiple choice

What was the name of the debate between Edward O. Wilson and Richard Dawkins about the role of natural selection in human evolution?

  1. The Sociobiology Debate

  2. The Wilson-Dawkins Debate

  3. The Human Evolution Debate

  4. The Biological Revolution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Sociobiology Debate was a debate that occurred in the late 1970s and early 1980s in which Edward O. Wilson argued that human behavior is influenced by natural selection. Richard Dawkins argued that human behavior is not influenced by natural selection.

Multiple choice

What was the name of the debate between Stephen Jay Gould and Richard Lewontin about the role of chance in evolution?

  1. The Punctuated Equilibrium Debate

  2. The Gould-Lewontin Debate

  3. The Evolution Debate

  4. The Biological Revolution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Punctuated Equilibrium Debate was a debate that occurred in the late 1970s and early 1980s in which Stephen Jay Gould and Richard Lewontin argued that evolution occurs in fits and starts, rather than gradually.

Multiple choice

D Correct answer
Explanation

Evolution encompasses the changes in heritable traits of biological populations over successive generations.

Multiple choice

What is the term used to describe the process by which organisms maintain a relatively stable internal environment despite changes in their external environment?

  1. Homeostasis

  2. Metabolism

  3. Adaptation

  4. Evolution
Reveal answer Fill a bubble to check yourself
