The Origin of Species
Darwin's theory is based on key facts and inferences drawn from them, which biologist Ernst Mayr summarized as follows:
Every species is fertile enough that if all offspring survived to reproduce the population would grow. (fact)
Despite periodic fluctuations, populations remain roughly the same size. (fact)
Resources such as food are limited and are relatively stable over time. (fact)
A struggle for survival ensues. (inference)
Individuals in a population vary significantly from one another. (fact)
Much of this variation is inheritable. (fact)
Individuals less suited to the environment are less likely to survive and less likely to reproduce. (inference)
Individuals more suited to the environment are more likely to survive and more likely to reproduce. (inference)
They will leave their inheritable traits to future generations. (inference)
This produces the process of natural selection. (inference)
This slowly effected process results in populations changing to adapt to their environments. (inference)
Ultimately, these variations accumulate over time to form new species. (inference)
