Are we still evolving? Microevolution: change in gene frequency - YES Macro evolution : formation of species - NO
Slide 55-

Are we still evolving? Some parts of Africa have seen an increase in the frequency of a gene called CCR5-32 Protects against infection with HIV-1. May have been selected for during bubonic plague
