<h2>Natural selection </h2>
Explanation:
Malthus's ideas about geometric population growth implied that: resources in every generation would be limited, therefore individuals in every generation would have to compete for those resources
- Thomas Malthus argued that the food supply increased linearly while population size increased exponentially
- The central theme of Malthus' work was that population growth would always overpower food supply growth, creating perpetual states of hunger, disease, and struggle
- The natural, ever-present struggle for survival caught the attention of Darwin, and he extended Malthus' principle to the evolutionary scheme
- Malthus’ writings ultimately inspired Darwin’s theory of evolution by natural selection
resources in every generation would be limited, therefore individuals in every generation would have to compete for those resources.

This should be considered a case of natural selection because humans were not selecting for particular desirable traits.
Explanation:
The individuals in the population who held even the slightest advantage in the tolerance of the oil spill had higher chances of surviving and passing their genes to the next generation. Fishes with low tolerance perished even before getting to maturity. Therefore with each generation, traits for oil tolerance in the population increased by natural selection enabling the population to evolve towards increased intolerance to oil over a period of several generations.
