What is the primary mechanism of evolution proposed by Charles Darwin?
Natural selection
True or False: Fossil records provide evidence for the gradual change of species over time.
True
Fill in the blank: The study of __________ provides insights into evolutionary relationships among species.
Comparative anatomy
Which type of evidence for evolution involves comparing the DNA sequences of different organisms?
Molecular evidence
What are homologous structures?
Body parts in different species that have a similar structure but different functions.
True or False: Vestigial structures are fully functional organs that have lost their original purpose.
False
What is an example of a vestigial structure in humans?
The appendix
Which type of evidence includes the geographic distribution of species?
Biogeographical evidence
What does the term ‘adaptive radiation’ refer to?
The rapid evolution of diversely adapted species from a common ancestor.
Fill in the blank: The __________ theory of evolution explains how species change over time due to environmental pressures.
Modern synthesis
True or False: Convergent evolution results in similar traits in unrelated species due to similar environmental pressures.
True
What is the significance of transitional fossils?
They provide evidence of the evolutionary links between different groups of organisms.
Which scientist is known for his work on the inheritance of traits and genetics in relation to evolution?
Gregor Mendel
What is the concept of ‘survival of the fittest’ often associated with?
Natural selection
Fill in the blank: The __________ of species is a key concept in understanding evolutionary relationships.
Common descent
What role do mutations play in evolution?
They introduce genetic variation in a population.
True or False: Artificial selection is a form of natural selection.
False
What is the difference between microevolution and macroevolution?
Microevolution refers to small-scale changes within a species, while macroevolution refers to larger evolutionary changes that result in new species.
Which type of evolution describes the process where related species evolve different traits?
Divergent evolution
Fill in the blank: The __________ is a measure of how much a species’ traits vary within a population.
Genetic diversity
What is the significance of the Galápagos Islands in the study of evolution?
They provided key insights into the process of natural selection through unique species adaptations.
What is a key factor that drives speciation?
Geographic isolation
True or False: Genetic drift can lead to significant changes in small populations over time.
True
