Strategies for Adaptation to Immediate Changes to Environment
What will be an ideal response?
•Adaptation strategy differs depending on timeline - seconds to generations.
•Long-term strategy = mutation, which can be beneficial but also risky.
-Issues with mutation:
•mutations occur randomly.
•Some traits require multiple mutations
•Not exactly reversible
•Short-term strategy = gene regulation, which is rapid and reversible.
