A murky pond with brown fish and orange fish has existed peacefully over many decades. Suddenly, a new predator crane has come to the area and loves to eat fish.
1. Explain how natural selection might work in this scenario and why?
2.Can an organism “will” itself to adapt to a new environment so it can increase its fitness?
Answers
1. The process in nature by which, according to Darwin's theory of evolution, only the organisms best adapted to their environment tend to survive and transmit their genetic characters in increasing numbers to succeeding generations while those less adapted tend to be eliminated. Here the crane is the superior species. And fishes are not superior hence will tends to wash out.
2. No.
1. Fishes, in general, lay a lot of eggs.
Over the years both the fishes must have laid many eggs and a large number of brown and yellow fishes will be there in the pond.
Therefore, even if a predator crane is there, it can hardly make much of a difference as the number of both the fishes must be very high by now.
Moreover, who knows, if someday, other predators may come in search of the crane itself.
2. Every organism creates its own ecosystem and survives according to it so that it can adapt to a new environment and gradually improve upon its fitness living over there.
It learns to adapt itself or modify as per the circumstances.
