What are the main factors that allow traits to become more common over time.
CFS:
accurately describes the relationship between environmental changes and population variations
describes the cause and effect relationship between environmental factors and species traits
Which trait is most likely to survive in an environment where waters are warmer?
Thin blubber is most likely to survive
Medium blubber is most likely to survive
Thick blubber is most likely to survive
It is impossible to determine the trait that is most likely to survive
Which trait is most likely to survive in an environment where waters are colder?
Thin blubber is most likely to survive
Medium blubber is most likely to survive
Thick blubber is most likely to survive
It is impossible to determine the trait that is most likely to survive
Identify the environmental change that best explains the differences in traits shown on the first page.
I think the environment got colder and thick blubber will become an adaptive trait over time because thick blubber will live longer and reproduce more.
I think the environment got colder and thin blubber will become an adaptive trait over time causing the population to increase.
I think the environment got warmer and thick blubber will become an adaptive trait over time allowing thick blubbered seals to reproduce more.
I think the environment got warmer and thin blubber will become an adaptive trait over time and will live longer and reproduce more.
