- Q2What is the study of the comparison of embryos from different species to understand evolutionary relationships called?GeneticsEmbryologyPaleontologyEcology30s
- Q3In the process of natural selection, what is meant by 'fitness'?The average lifespan of an organismThe strength of an organismThe ability of an organism to survive and reproduce in its environment.The size of an organism30s
- Q4What is the process by which organisms better adapted to their environment tend to survive and produce more offspring?MutationGene flowNatural selectionGenetic drift30s
- Q5What term describes small evolutionary changes that occur within a species over time (years)?AdaptationSpeciationMacroevolutionMicroevolution30s
- Q6Which of the following best describes macroevolution?Changes in allele frequenciesAdaptations to a specific environmentLarge-scale evolution that leads to the formation of new species over long periods (million years)Evolution that occurs within a population30s
- Q7What is the term for the process by which an organism becomes better suited to its environment?EvolutionAdaptationMutationNatural selection30s
- Q8What type of selection occurs when certain traits increase an individual's chance of attracting a mate? Think of a peacock colorful feathers to attract mateNatural SelectionSexual SelectionDirectional SelectionArtificial Selection30s
- Q9What structures in the body are reduced in size and function but provide evidence of evolution?Vestigial StructuresAnalogous Structures30s
- Q10What is the movement of genes between populations due to migration, which can affect genetic diversity? remember the beads when I added extra random beadsGenetic DriftMutationGene Flow30s
- Q11Which type of evolution occurs when two or more species that share a common ancestor evolve different traits or functions?Convergent EvolutionCo-evolutionParallel EvolutionDivergent Evolution30s
- Q12What is it called when a population of organisms changes over time to better survive in their environments?FossilizationAdaptationExtinction30s
- Q13What are structures in different species that have a similar origin but may have different functions, illustrating common ancestry?Homologous StructuresFossilsVestigial Structures30s
- Q14What term refers to the process by which individuals with favorable traits are more likely to reproduce, leading to those traits being passed on to future generations?Genetic DriftSexual SelectionNatural SelectionMigration30s
- Q15What is the process through which species adapt to their environment over generations, often leading to the development of new species?MacroevolutionNatural SelectionMicroevolutionGenetic Drift30s
