FQ: How does natural selection lead to adaption in populations?
Environment: cave organism:bear Adaption: chasing down prey Adaption type: physical
Principle 1: Genetic Variation
Natural selection limits down to the strongest of the fittest to survive and adapt to their environment
Principle 2: overproduction and the struggle to survive
This adaption of of having long and strong back near the hind legs makes them fast and efficient for attacking their prey.
Principle 3: Survival and reproduction of the fittest
In the environment, there are bears that have strong legs and back and are larger in size. Then there are the small, weaker one that do not have as strong of legs and back as the other bears.
Principle 4: Changes in the Gene Pool
The faster and stronger bears are able to chase down their prey quicker that the weaker bears, leaving the weaker bears with limited food supply.
The strongest of the fittest, the stronger legged bears, are surviving more then the weaker legged bears because of their of their fast twitch genes. The weaker bears are dying out and the stronger bears' population is expanding.
The gene pool of the environment has change to the majority of population consisting of the stronger back and fast twitch genes. Natural selection made it possible for the strong bears to adapt to their environment, fulfilling the process of evolution along the way.
