Across
  1. 6. are anatomical features that are reduced or completely useless in a particular species but have been inherited from a common ancestor that had a function for them.
  2. 9. refers to changes in an organism's physiological processes, such as metabolism or immune function, that allow it to better survive and reproduce in its environment.
  3. 13. refers to a process by which organisms develop traits that allow them to better survive and reproduce in their environment.
  4. 14. refers to physical changes in an organism's anatomy that allow it to better survive and reproduce in its environment.
  5. 15. is a form of adaptation in which an organism has evolved to blend in with its environment, typically for defensive purposes.
  6. 16. is the intentional selection and breeding of plants or animals by humans to produce offspring with desired traits or characteristics.
  7. 17. as it relates to evolution, refers to a change in the DNA sequence of an organism's genome that can give rise to new variations of traits that may be better suited to a particular environment.
  8. 18. the process by which certain heritable traits that are better suited to a particular environment become more common in a population over time, while less advantageous traits become less common, as organisms with the more beneficial traits are more likely to survive and reproduce.
Down
  1. 1. refers to the process by which some individuals in a population are more successful at reproducing than others, leading to a shift in the population's genetic makeup over time.
  2. 2. was a French naturalist who is best known for his theory of inheritance of acquired characteristics, which proposed that traits acquired during an organism's lifetime could be passed down to its offspring. Although Lamarck's theory has been discredited, his work on the classification of invertebrate animals and his early ideas about evolution paved the way for later evolutionary thinkers.
  3. 3. was a British naturalist and biologist who is best known for his contributions to the theory of evolution through natural selection. In 1859, he published "On the Origin of Species," which introduced the concept of natural selection as the driving force behind evolution.
  4. 4. the gradual process by which populations of organisms change over time through a combination of genetic variation, natural selection, and other mechanisms, ultimately leading to the development of new species.
  5. 5. is a measure of an organism's ability to survive and reproduce in its environment.
  6. 7. are structures in different species that have similar functions but have evolved independently, rather than being derived from a common ancestor.
  7. 8. is a form of adaptation in which an organism has evolved to resemble another species, typically for defensive purposes.
  8. 10. are anatomical features in different species that share a common evolutionary origin, having derived from a common ancestor with the same basic structure.
  9. 11. refers to random fluctuations in the frequency of alleles in a population due to chance events, such as genetic mutations or changes in the environment.
  10. 12. refers to the movement of individuals from one population to another, which can impact the genetic diversity of both populations and potentially lead to speciation.
