Darwin's observations:

 

1. All organisms produce more offspring than survive to adulthood.

 

2. Organism populations remain more or less constant in number.

 

3. In the same species there is variation of traits between individuals.

 

4. Some adaptations are inherited by the offspring and are so passed on to the next generation 

I going to a talk 'bout prime numbers, bye bye Rawry :)

 

g'bye

Deductions:

 

All organisms are involved in a constant struggle for survival and only the best adapted will survive

 

Organisms that  survive are more likely to reproduce, thus passing on their useful adaptations to their offspring

Similarities between artificial and natural selection:

 

both bring forward specific adaptation

both are possible because of inherited traits

both occur because of external pressures

both are based in changes of the gentic code of organims and the phenotypic expression of that code

organisms can survive and reproduce

can bring about speciation

differences:

 

human caused vs nature caused

natural relies on death of unfit organisms, and artificial on the reproduction of fit organisms

artificial selection does not necessarily select traits that are fit in a natural environment
