9. continuing to live or exist, especially after facing difficulties or dangers
11. the study of the evolutionary history and relationships of different species or groups of organisms
13. organisms with traits better suited to their environment are more likely to survive and reproduce, passing on those advantageous traits to their offspring
15. the understanding that populations of living organisms change over time, primarily due to natural selection

1. the complete disappearance of a species from Earth
2. an organism's ability to survive and reproduce in a given environment, ultimately contributing to its ability to pass on its genes to the next generation
4. he process by which humans actively choose which individuals in a population will reproduce, typically based on desirable traits, leading to changes in the genetic makeup of the species over time
5. the gradual and ongoing changes in society's structures, behaviors, and institutions over time
8. an ethical theory that claims that humans are born with a certain moral compass that guides behaviors
10. the process by which organisms, including animals and plants, change or adjust to better suit their environment and improve their chances of survival and reproduction
12. the change in the characteristics of populations of living things over many generations
14. a permanent change in the DNA sequence of an organism, which can lead to alterations in traits.
