Evolution Evaluation

Define evolution:
The gradual development of something, especially from a simple to a more complex form.

How does evolution work ?
Evolution is driven by the fact that all organisms have to struggle to survive long enough to reproduce in a world filled with predators, disease, and competition for resources. To survive, an organism may have many offspring that are equally successful in reproduction; others must avoid being eaten or killed by disease. They must compete for food and, perhaps, even a mate. Having mated, it must then ensure its offspring’s survival. Some organisms live long enough to reproduce, and some of these produce fewer offspring, or even die before they can reproduce. Those that reproduce and create successful offspring are more ‘fit’ for survival than those that don’t. The characteristics that helped this ‘fitness’ will be more common in the next generation than those of its less ‘fit’ relatives. This process is called natural selection.

What is natural selection ?
The process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.

Who came up with the idea of evolution ?
Charles Darwin

How was the idea motivated? When was it motivated ? What motivated it ?
It took Charles Darwin so long to publish his theory, nearly 23 years, because…
