it's hard to estimate that very accurately because the human genome is a moving target - each new human has maybe 100 new mutations of which 1 or 2 will affect coding DNA. i will just consider single nucleotide polymorphisms (SNPs), which are defined to be variances in the identity of a single nucleotide occuring in at least 1% of the population. there are about 3 million of those, of which about 60,000 affect coding DNA so that the humans that developed would not be identical. so there are 60,000 ways of having 1 SNP. there are 59,999 ways of having a second SNP, totalling about 3.6 billion ways. for three SNPs the total number of ways is about 216 trillion, far more than the number of humans that have ever lived. most people probably have have several thousand coding SNPs, so you can see that the possible number of non-identical humans is very very large.

A problem-unfastened theory-approximately species is that diverse species do no longer interbreed and form fertile offspring, that's needed for evolution. Apes and people are diverse species, so interbreeding would not produce a fertile offspring. extra beneficial, a breeding in all likelihood would not produce an organism which could strengthen previous some cellular point because it might have a pair of unequalled chromosomes. The assertion that the chromosome variety could no longer replace is inaccurate. The style of chromosomes can replace by way of non-disjunction, despite if it is many times deleterious. there became a sort of "manimal" at one time. It became the primate progenitor of the primates alive immediately. countless branches of the tree stemming from that organism died off earlier some proceed to be (us, apes, chimps and different variations of primates). there is not any requirement that a lacking link could be alive immediately for us to be certain it to make certain that evolution to be actual. There are classifications of fingerprints (whorls, swirls, etc.) so there are some similarities between diverse people despite if, the right wrinkle types are diverse between people as they do no longer seem to be completely genetically desperate. the possibilities are very, very small that 2 people would have the right same fingerprint development. the possibilities that each and every thing on the earth are completely valuable to people is rather low. the 1st element that contains suggestions is the mosquito that bit me final night. i would not placed that interior the class of valuable. i'd placed it interior the class of ecology in that there is an atmosphere and we are all (which potential all organisms) based on one yet another in some form or style. i'm satisfied you sense convenience from God. there is not any requirement that God and evolution be collectively unique nor that is worthwhile to have confidence in a single and not the different.
