Darwin contributed an explanation of a mechanism by which organisms change over time, that is, an explanation of how organisms evolve. The idea that he proposed is "natural selection" and includes the following ideas:
First, within any population of organisms there is variation.
Second, some of this variation is genetically transmitted from one generation to the next.
Individuals with some types of variation will be better able to pass those varations to their offspring. That is, some individuals will produce more offspring than others.
Over time, because of this differential reproduction, the genetic makeup of the population of organisms will change.
In a nut-shell, that is the Theory of Evolution.

Back in Darwin's day, people had figured out that species evolve, but the problem of why they did had not been figured out. Darwin's hypothesis was that those organisms who were more fit were the ones that survived, so with time the population became more like those which were most fit. Here "fit" means best able to reproduce and support the offspring. His contribution to modern science is that now all biologists consider the evolutionary importance of something when they are attempting to explain it.

Charles Darwin came up with the idea of 'natural selection' which later sprang into the theory of evolution. Natural selection is basically 'the strong survive'.
Remember this remains a theory, which is a contribution but not a fully proven one. Other theories that are in the same subject as Darwin's are the ideas of creationism, which are basically religious beliefs based on scriptural reference (The Bible etc.)

Not just contributions to modern science, but for all time; he answered the question, " why is man ".

The concept of "Natural Selection" as a driving force for the changes in isolated populations over a period of time, leading to speciation.
He also wrote a nice book about earthworms and how they "make" soil.

He done a quickie with Origin of Species because his associate was onto the same idea. He also built on Lammarcks ideas a lot. I guess if you're thinking about what his theory has done for science, well it's essentially the basis of a lot of mondern biological concepts.

Honestly, in my opinion, Darwin contributed nothing to modern science.

He answered the question of where liberal Democrats come from. Unfortunately they are still monkeys.

Perhaps a click on wikipedia.org would help, instead of expecting us to do it for you.
