Natural Selection Is Not Simply Survival of the Strongest
Natural selection favours traits that improve reproductive success in a given environment — not raw strength alone. A weaker but better-camouflaged individual may leave more offspring than a strong, conspicuous one.
Core ingredients
- Variation in the population
- Heredity of some of that variation
- Differential survival and reproduction
- Change in trait frequencies over generations
Selection pressure depends on the environment. What is advantageous in a drought may not be advantageous in a flood year.
A Level Biology tutors in DHA Islamabad can replace slogan definitions with short selection scenarios students must explain step by step.
