Evaluation summative practice Flashcards
How does natural selection lead to evolution over time?
Natural selection results in changes in species’ traits over generations.
What are real-world examples of natural selection in action?
Examples include antibiotic resistance in bacteria and changes in beak size in finches.
What is the difference between artificial and natural selection?
Artificial selection is human-directed, while natural selection occurs through environmental pressures.
What impact does artificial selection have on species over time?
Artificial selection can lead to rapid changes in species traits and loss of genetic diversity.
What types of adaptations can be identified in organisms?
Adaptations can be structural, behavioral, or physiological.
How do adaptations help species survive in different environments?
Adaptations enhance survival and reproduction in specific ecological niches.
What is a phylogenetic tree?
A diagram that shows evolutionary relationships among various biological species.
What evidence supports human evolution?
Fossil and genetic evidence provide substantial support for the theory of human evolution.
What types of evidence exist for evolution?
Types of evidence include fossils, anatomy, embryology, and genetics.
What can be observed in zebrafish embryo development?
Zebrafish embryo development provides embryological evidence for evolution.
How has the misuse of evolutionary science led to unethical practices?
Misuse has resulted in practices like eugenics, which exploit evolutionary concepts.
Why is it important to distinguish science from pseudoscience?
Distinguishing helps maintain scientific integrity and public understanding of science.
How do bacteria evolve resistance to antibiotics?
Bacteria evolve resistance through natural selection favoring resistant strains.
What are public health strategies to combat bacterial evolution?
Strategies include prudent antibiotic use, vaccination, and infection control.
