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
What is the problem of altruism, in the context of evolutionary psychology?
-
Altruism is not adaptive and therefore cannot be explained by evolutionary theory
-
Altruism is too common to be explained by evolutionary theory
-
Altruism is only possible in small, closely-knit groups
-
Altruism is only possible if it is reciprocated
A
Correct answer
Explanation
The problem of altruism is that it appears to be maladaptive, as it involves sacrificing one's own fitness for the benefit of others.
How do evolutionary psychologists explain the problem of moral diversity?
-
By arguing that moral norms are not universal, but rather are culturally specific
-
By arguing that moral norms are often adaptive in the context in which they evolved
-
By arguing that moral norms are often the result of historical accidents
-
All of the above
D
Correct answer
Explanation
Evolutionary psychologists explain the problem of moral diversity by arguing that moral norms are not universal, but rather are culturally specific, that they are often adaptive in the context in which they evolved, and that they are often the result of historical accidents.
What is the problem of moral progress, in the context of evolutionary psychology?
-
Moral norms have not changed over time
-
Moral norms have changed for the worse over time
-
Moral norms have changed for the better over time
-
Moral norms have changed in a random and unpredictable way
C
Correct answer
Explanation
The problem of moral progress is that moral norms have changed for the better over time, which is difficult to explain from an evolutionary perspective.
How do evolutionary psychologists explain the problem of moral progress?
-
By arguing that moral norms are not fixed, but rather are constantly evolving
-
By arguing that moral norms are often adaptive in the context in which they evolved
-
By arguing that moral norms are often the result of cultural learning and transmission
-
All of the above
D
Correct answer
Explanation
Evolutionary psychologists explain the problem of moral progress by arguing that moral norms are not fixed, but rather are constantly evolving, that they are often adaptive in the context in which they evolved, and that they are often the result of cultural learning and transmission.
Which of the following is NOT a biological theory of aging?
-
The free radical theory
-
The telomere theory
-
The genetic theory
-
The psychological theory
D
Correct answer
Explanation
The psychological theory of aging is not a biological theory. It focuses on the psychological and social factors that influence the aging process.
What is the Panspermia Hypothesis?
-
The hypothesis that life on Earth originated from extraterrestrial sources
-
The hypothesis that life on Earth originated from a single cell
-
The hypothesis that life on Earth originated from a comet or asteroid
-
The hypothesis that life on Earth originated from a volcanic eruption
A
Correct answer
Explanation
The Panspermia Hypothesis proposes that life on Earth originated from extraterrestrial sources, such as comets, asteroids, or meteorites, that carried microorganisms or organic molecules to our planet.
What is the evidence supporting the Panspermia Hypothesis?
-
The presence of organic molecules in meteorites and comets
-
The discovery of extremophiles on Earth
-
The similarities between life on Earth and life on other planets
-
The existence of fossils of extraterrestrial life
A
Correct answer
Explanation
The presence of organic molecules, which are the building blocks of life, in meteorites and comets is one of the strongest pieces of evidence supporting the Panspermia Hypothesis.
What are the implications of the Panspermia Hypothesis for the origin of life on Earth?
-
It suggests that life on Earth is not unique
-
It suggests that life on Earth is the result of a cosmic accident
-
It suggests that life on Earth is the result of a deliberate act of creation
-
It suggests that life on Earth is the result of a combination of factors
A
Correct answer
Explanation
The Panspermia Hypothesis suggests that life on Earth is not unique, as it proposes that life originated from extraterrestrial sources and may exist elsewhere in the universe.
Which philosophical approach emphasizes the importance of understanding the historical and evolutionary context in which biological systems have developed?
-
Historicism
-
Reductionism
-
Holism
-
Emergentism
A
Correct answer
Explanation
Historicism is the philosophical approach that emphasizes the importance of understanding the historical and evolutionary context in which biological systems have developed.
What is the name of the process by which organisms adapt to their environment over time?
-
Evolution
-
Natural selection
-
Adaptation
-
Speciation
A
Correct answer
Explanation
Evolution is the process by which organisms adapt to their environment over time.
What is the term used to describe the process by which species adapt to changes in their environment?
-
Evolution
-
Adaptation
-
Natural selection
-
All of the above
D
Correct answer
Explanation
Evolution, adaptation, and natural selection are all terms used to describe the process by which species adapt to changes in their environment.
What is the term used to describe the process by which species adapt to changing environmental conditions?
-
Natural selection
-
Evolution
-
Adaptation
-
Acclimatization
C
Correct answer
Explanation
Adaptation refers to the process by which organisms adjust to their environment over time, allowing them to survive and reproduce in changing conditions.
What is the purpose of phylogenetic tree construction in computational biology?
-
To identify the evolutionary relationships among different species
-
To predict protein structures
-
To design new drugs
-
To analyze gene expression data
A
Correct answer
Explanation
Phylogenetic tree construction aims to infer the evolutionary history and relationships among different species.
What is the term used to describe the process by which species adapt to new environmental conditions, including climate change?
-
Adaptation
-
Evolution
-
Natural selection
-
All of the above
A
Correct answer
Explanation
Adaptation refers to the process by which species change over time in response to new environmental conditions, including climate change.
What is the term used to describe the process by which organisms become better suited to their environment?
-
Adaptation
-
Evolution
-
Natural selection
-
Genetic drift
A
Correct answer
Explanation
Adaptation refers to the process by which organisms become better suited to their environment through the accumulation of favorable genetic changes.
