That theory—”pangenesis”—was an attempt to explain variation among individuals in a species. Offspring in sexual species display a mix of traits from both of their parents. Darwin’s observations that led to his theory of natural selection are: Overproduction – all species will produce more offspring than will survive to adulthood. Variation – there are variations between members of the same species. Adaptation – traits that increase suitability to a species’ environment will be passed on.Charles Darwin was born in Shropshire, England in 1809.
