-> WHICH must be preceded by a noun, not by a clause = Modifier issueNeanderthals didn't live in Africa, which is why sub-Saharan African populations have no trace of Neanderthal DNA, but other populations share DNA with Neanderthals, as discovered by a paleogeneticist at the Max Planck Institute in Germany that sequenced the Neanderthal genome.
-> a paleogeneticist.....Germany that sequenced... = Weird
(B)
-> Maintains perfect S-V agreement and retains the authors meaning. (CORRECT)Having sequenced the Neanderthal genome, a paleogeneticist at the Max Planck Institute in Germany has concluded that any human whose ancestral group developed outside Africa has inherited DNA from Neanderthals; since Neanderthals didn't live in Africa, sub-Saharan African populations have no trace of Neanderthal DNA.
(C)
-> WHICH must be preceded by a noun, not by a clause = Modifier issueNeanderthals didn't live in Africa, which is why sub-Saharan African populations have no trace of Neanderthal DNA, but a paleogeneticist at the Max Planck Institute in Germany who sequenced the Neanderthal genome has concluded that other humans share DNA with Neanderthals.
-> a paleogeneticist....in Germany who... = Modifier problem(Looks like a misplaced modifier)
(D)
After sequencing the Neanderthal genome, the Max Planck Institute in Germany where a paleogeneticist researched the Neanderthal-human link, has concluded that any human whose ancestral group developed outside Africa has inherited DNA from Neanderthals; since Neanderthals didn't live in Africa, sub-Saharan African populations have no trace of Neanderthal DNA.
-> Meaning issue (It is the paleogeneticist who has concluded, not the Max Planck Institute(Subject))
(E)
-> Meaning issue ("Sequencing" is used as a noun replacement, so it seems to be "the sequencing...has led to the conclusion..." which is illogical. It is the paleogeneticist who has concluded)The sequencing of the Neanderthal genome by a paleogeneticist at the Max Planck Institute in Germany has led to the conclusion that humans whose ancestral group developed outside Africa has inherited DNA from Neanderthals and sub-Saharan Africans have no trace of Neanderthal DNA due to Neanderthals not living in Africa.
-> S-V agreement issue (humans ... has inherited)
