Micro and macro evolution are not the same thing, but it's okay because it appears that lots of people make this mistake. Micro evolution is the change in allelic frequencies over time (example: B and b code for skin color. Over ten years the allelic freaquencies change from b=.50 B=.50 to B=.75 b=.25 in a population of desert nomads) . Macro evolution is the change in phenotypic variation for a select population of a species(example: genotypes(frequencies) code for phenotypes(individuals or whole numbers). Over 10 years the genotypic variation of the 100 desert nomads change from BB=.25 Bb=.5 bb=.25 or phenotypically BB=25 Bb=50 bb= 25 where B and b are codominant, BB codes for dark skin, Bb codes for tan skin and bb codes for white skin. In 10 years, the 100 individuals change to BB= .70 Bb=.3 bb= 0 or phenotypically BB=70 Bb=30 bb=0. This indicates directional selection for darker skin tone due to the environment.) welcome to population genetics 101. For the sake of the argument, the numbers do not match up for anyone who knows this and want to check this with Hardy-Weinburg. This is merely an example to teach people.
