Question

1. The Neanderthal is an extinct group of hominids (evolutionarylineages closely related to that of modern humans). Neanderthalsremains are estimated to be about 30,000 years old. Geneticistsextracted DNA molecules from those Neanderthals bones and foundthat Neanderthal DNA sequences are different from modern humans byabout 0.5%. Humans and chimps are estimated to have shared theirlast common ancestor about 5 million years ago and their DNAsequences are different by about 5%. Based on this information andassuming the same molecular clock, can you confirm or reject thehypothesis that Neanderthals are the direct ancestor of modernhumans? Briefly explain.

Explanation / Answer

Accept the hypothesis thatNeanderthals are the direct ancestor of modern humans as Geneticists extracted DNA molecules from thoseNeanderthals bones and found that Neanderthal DNA sequences aredifferent from modern humans by about 0.5%. Humans and chimps areestimated to have shared their last common ancestor about 5 millionyears ago and their DNA sequences are different by about 5% basing upon above data at 5% level ofsignificance , we can Accept thehypothesis that Neanderthals are the direct ancestor of modernhumans
