How is evolution measured?
I’m looking for something that expresses evolution directly instead of adressing the time and extent of the evolution seperately. Something like “Losing their tails cost humans 4 Darwins”??? With the length of a single Darwin depending on birth rates and total fertility rates. Of course the chance of the mutation would have to be in there as well but I’m mostly wondering if something like this exists already?
