you know, our existence would seem to be amazingly improbable, because there's an enormous number of genetically possible humans, if you can compute it by looking at the number of the genes and the number of alleles and so forth, and a back-of-the-envelope calculation will tell you there are about 10 to the 10,000th possible humans, genetically.
Saben, nuestra existencia parece ser poco probable, porque hay una enorme cantidad de humanos genéticamente posibles, si se puede calcular mirando el número de genes y alelos, así sucesivamente, y un cálculo ligero dirá que hay unos 10 a la 10 000 humanos genéticamente posibles.
