What is the theory of evolution by natural selection?

The theory of evolution by natural selection explains how species evolve over time through the process of adapting to their environment. This concept, proposed by Charles Darwin, highlights how individuals with advantageous traits are more likely to survive and reproduce, leading to changes in the population over generations.

Natural selection occurs when individuals with certain traits have a better chance of surviving and reproducing in their environment. These advantageous traits are often passed on to the next generation, leading to an increase in the frequency of those traits within the population.

Charles Darwin and evolution

Charles Darwin, a renowned naturalist, proposed the theory of evolution by natural selection in his book "On the Origin of Species" in 1859. His revolutionary ideas challenged prevailing beliefs about the origins of species and sparked a new era in evolutionary biology.

Through the process of natural selection, species undergo changes over time as they adapt to their environment. Genetic variation within populations allows for the emergence of new traits, which can be selected for or against based on their impact on an individual's ability to survive and reproduce.

In essence, the theory of evolution by natural selection emphasizes the survival of the fittest individuals within a population, ultimately leading to changes in the genetic makeup of species and the diversity of life on Earth.
