The genome revolution of the last two decades has enabled scientists to analyse
whole genomes of people from many living human populations. Genetic material
has also been extracted from the bones of Neanderthals and Denisovans.
Neanderthals and Denisovans are regarded by evolutionists as different species
from present humans, but gene variants found in them, have also been found in
people living all over the world.

Several groups of evolutionary scientists are now trying to
put all this genetic information together to build an evolutionary tree of
mankind from ape-like ancestors. This has proven difficult, so they have
theorised that modern humans are descended from a mysterious “ghost” population
of “super-archaic” humans who interbred with Neanderthals and Denisovans.

According to Science News, “At least two super-archaic ‘ghost’ hominins interbred with the ancestors of Neanderthals, Denisovans, and modern humans. Later, those three groups also met and mingled, leaving complex traces in each other’s genomes”.

Editorial Comment: This is not the first time the concept of “ghost ancestors” or “ghost lineages” has been used in evolutionary theory. It has been used whenever evolutionists are unable to fit evidence found in the real present-day into their imagined past evolved history of the planet. If they recognised the real history of the world, as revealed by the One who has been there all the time, they wouldn’t need to invoke such unscientific ghosts.

The reason Neanderthal and Denisovan gene variants are found in living human populations is that both groups were fully human. Let’s be blunt: mankind did not begin with super-archaic ghosts, but with one very real human couple, Adam and Eve. All people who have ever lived are their descendants, so there is, and always has been only one human kind. At the time of Noah’s Flood the human population was reduced to the eight people of Noah’s family. Their descendants were split up into subgroups after judgement at the Tower of Babel. These subgroups spread out over the earth and became the ancestors of the many different ethnic and cultural groups who have ever lived since then. Some groups, such as Neanderthals and Denisovans, many have died out, but that does not make them different species.
