Question

Can anyone explain to me, Charles Darwin's Theory of Natural Selection?

Answer 1

No. I think he meant survival of the fitest and strongest. That is natural selection.

Answer 2

Its simple really, survival of the fittest.  Taken in a moment of time it is meaningless.  But taken over thousands of generations, the best physical and adaptive characteristics of each species will push out the weaker and less adaptive characteristics.  

So, in a more global perspective, species will change to best take advantage of their environment.  Those that cannot change will become extinct.

Answer 3

Antiseptic hand cleaners are popular. "Waterless formula kills 99.9% of germs" is a common claim. So, what happens to th remaining 1%? The short answer is they breed, produce the nature generation of germs, and have some resistance to Antiseptic hand cleaners!

This is natural selection. In a species, the individuals that best meet the demands of their enviorment are most likely to reproduce.

Gypsy moths in England used to be light colored. With the industrial revolution, soot darkened buildings and vegetation. The light colored moths were easily found and eaten. Moths that were slightly darker lived and reproduced. The trait of being darker was passed on to the next generation of moths. Soon (in geologic time) most gypsy moths were dark colored and matched well with the enviorment.

The basics are:

"1.There is variation in traits.

For example, some beetles are green and some are brown.

2. There is differential reproduction.

Since the environment can't support unlimited population growth, not all individuals get to reproduce to their full potential. In this example, green beetles tend to get eaten by birds and survive to reproduce less often than brown beetles do.

3.There is heredity.

The surviving brown beetles have brown baby beetles because this trait has a genetic basis.

  

4. End result:

The more advantageous trait, brown coloration, which allows the beetle to have more offspring, becomes more common in the population. If this process continues, eventually, all individuals in the population will be brown.

Note that natural selection isn't a plan. The individual that best copes with the environment will have the best chance to reproduce and pass their traits on.

Answer 4

1 creatures are different

2 those differences effect their ability to survive and reproduce.

3 the differences that make a creature better at surviving and reproducing will become more common than the ones that hurt the creatures ability to survive and reproduce.
