Wraz z odkryciem doboru naturalnego Darwin sprowadził zagadnienie pochodzenia i przystosowania organizmów do sfery nauki. Adaptacyjne cechy organizmów można obecnie wyjaśnić, podobnie jak zjawiska świata nieożywionego,...

Yet, that living organisms, including humans, have evolved from ancestors who were very different from them is beyond reasonable doubt, confirmed by at least as much evidence as any other widely accepted scientific theory. I argue that Darwin’s...
We have examined the patterns of polymorphism at two linked loci, Sod and Est-6, separated by nearly 1000 kb on the left arm of chromosome 3 of Drosophila melanogaster. The evidence suggests that natural selection has been involved in shaping the polymorphisms. At the Sod locus, a fairly strong (s>0.01) selective sweep, started ≥2600 years ago, increased the frequency of a rare haplotype, F(A),...
