5 MAJOR IDEAS ON Charles Darwin

1. organisms within a population must compete for resources to survive. (Food, water, space,

breeding partners, etc)

2. organisms within a population exhibit variations (size, shape, color, resistance to disease, etc)

3. some variations will enhance a particular organisms ability to compete for resources or survive

adversity.

4. Those organisms with beneficial variations are more likely to survive and pass their characteristics

on to their offspring.

5. Over time these variations will spread through each generation to a larger and larger portion o

f the population thus gradually changing the population as a whole.

Of course Darwin did not know about DNA genetics etc. (Making his work all the more remarkably)

It was the re-discovery of Mendel's work on heredity and later work by men such as Watson and

Crick on DNA as the genetic material that allowed us to flesh out the details of Darwin's' theory

PS...contrary to many answers above...Darwin's theory of Evolution had NOTHING to do with the

origin of life...that's called ABIOGENESIS.

The theory of evolution.
