Natural Selection n Selection is the only evolutionary mechanism that leads to nonrandom changes in allele frequencies. n Natural selection can increase.

Towards a synthesis between Adaptive Dynamics and Evo-Devo as the two main “postmodern” approaches to macro-evolution EEP (fo rmerly ADN ) IIASA Hans Metz.
Genetic Drift In small, reproductively isolated populations, special circumstances exist that can produce rapid changes in gene frequencies totally independent.
Non-random mating n Mating in many species is often assortative Humans provide lots of examples Humans tend to marry people of similar intelligence Humans.
