Test 1 Flashcards
What is the theory of evolution?
The theory of evolution explains how species change over time through processes like natural selection and genetic drift.
Who is known as the father of evolution?
Charles Darwin is known as the father of evolution.
What is natural selection?
Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.
True or False: Evolution occurs in individuals.
False: Evolution occurs in populations over generations.
Fill in the blank: The concept that all species are related through common ancestry is known as _______.
descent with modification.
What is adaptation in the context of evolution?
Adaptation is the process by which a species becomes better suited to its environment through changes in traits.
Multiple Choice: Which of the following is a mechanism of evolution? A) Mutation B) Natural Selection C) Genetic Drift D) All of the above
D) All of the above
What role do fossils play in the theory of evolution?
Fossils provide evidence of past life forms and show how species have changed over time.
True or False: Evolution is a linear process.
False: Evolution is not linear; it can take many paths and is influenced by various factors.
What is genetic drift?
Genetic drift is a mechanism of evolution that involves random changes in allele frequencies in a population.
Fill in the blank: The process by which organisms produce more offspring than can survive is called _______.
overproduction.
What is the significance of the peppered moth in studies of evolution?
The peppered moth demonstrates natural selection in response to environmental changes during the Industrial Revolution.
Explain the term ‘survival of the fittest’.
‘Survival of the fittest’ refers to the idea that individuals best adapted to their environment are more likely to survive and reproduce.
Multiple Choice: Which scientist developed the concept of ‘punctuated equilibrium’? A) Charles Darwin B) Stephen Jay Gould C) Gregor Mendel D) Richard Dawkins
B) Stephen Jay Gould
What is the difference between microevolution and macroevolution?
Microevolution refers to small evolutionary changes within a species, while macroevolution involves large-scale changes that can lead to the formation of new species.
True or False: All adaptations are beneficial.
False: Some adaptations may be neutral or even detrimental in certain environments.
What is a common misconception about evolution?
A common misconception is that evolution is a purposeful process; in reality, it is driven by random mutations and natural selection.
