Question

What are some examples of the survival of the fittest?

Answer 1

Concept of Survival of the Fittest:

1. Survival of the fittest is a concept that comes from the theory of natural selection by Charles Darwin.
2. Most organisms produce many offspring, which compete with the limited resources such as food, water, and shelter.
3. There is also genetic variation among species which can be passed on to the next generation.
4. These variations introduce characteristics that will give the organism a better chance at survival and reproduction.
5. After many generations, the population changes as it carries the beneficial characteristic.
6. Therefore, survival of the fittest means that organisms that can adapt to their environment have a greater chance of survival and passing on their beneficial genes to their offspring.

Examples of survival of the fittest concept:

The Industrial Revolution in London :

1. The Industrial Revolution in London started to deposit soot on the trees.
2. The wings of the moths that lived on the trees were light-colored.
3. They adapted themselves, and the wing color became darker to blend with the surroundings and protect them from predators.

The Galapagos finches:

1. There is variation among species, and there are circumstances when specific hereditary characteristics benefit the organism more.
2. This means that one variant of the species will have a better chance of survival in a particular scenario.
3. The Galapagos finches have large beaks that are suitable for drought conditions and small beaks that are suitable for rainy conditions.
4. Hence, the climatic conditions will be the deciding factor for which species will survive in the habitat.
