Evolution does not mean that over time a species becomes “better” somehow, and evolution does not progress in a predetermined direction. In addition, traits acquired by individuals during their lifetime cannot be passed on to offspring. ...

Epigenetic Inheritance, Genetic Assimilation and Speciation
... Epigenetic inheritance systems enable the environmentally induced phenotypes to be transmitted between generations. Jablonka and Lamb (1991, 1995) proposed that these systems have a substantial role during speciation. They argued that divergence of isolated populations may be "rst triggered by the a ...
