Still, getting 7 lineages out of 2 people is going to be difficult.
It would be extremely difficult to get any different lineages out of two people if every child of the first couple were exact clones of their two parents. Which leads to the question, can one child be a clone of two people?
It comes down to the scientific observation of material/physical living organisms. Differences between species and differences within species can only occur if there are changes in DNA. One way to study these changes in humans is to examine the order or sequence of adenine, thymine, guanine, and cytosine base pairs. The human genome can contain 3 billion chemical base pairs that make up human DNA.

One interesting fact about the Human Genome Project is that there is no typical human genome because humans are not clones, they are separate individuals. Thus,
in determining a sample human genome, various common sequences are used. When scientists use places like GenBank to obtain genetic information, they give certain specifications about the DNA. For example, research papers often list the areas which are the source for the DNA samples. Or researchers might ask for DNA samples from a specific ethnic group.
Please note that the information above does not address how each species originated in the first place.
What it does address is the present diversity in our human population. No matter how one looks at human origin, once the first human person Adam came to be, he was subject to the laws of creation including the changes which normally occur in living material anatomies.
The following is from the news article linked in post 1.
Cardinal Pell said humans “probably” evolved from Neanderthals but it was impossible to say exactly when there was a first human. “But we have to say if there are humans, there must have been a first one,” he said.
Those who base their observations on only the material/physical universe (without knowledge of God’s power) are limited to the assumption that current changes in the 3 billion base pairs which are part of DNA followed a similar pattern present in the first generations of the human species. Yet at the same time, singular past environmental events like the Toba catastrophe have to be considered. The assumption that the process of change never altered from day 1 is not realistic especially when known situations like the “founder effect” influenced by natural adaption could have changed the rate of improvements in DNA or conversely the “founder effect” could have led to extinction. Even the length of generational time does vary depending on how the researcher views a simulated population.
This all boils down to the fact that the researcher chooses the particular data for computer simulated populations. Eventually, mathematical formulas are devised to explain what people think was happening thousands of years ago. This is acceptable when one is limited to knowledge from the material/physical world.
Thus, we have some crucial questions –
1.Are humans limited to knowledge from the material/physical world?
2.Does this limited knowledge from the material world necessarily, absolutely exclude all knowledge of the spiritual world?
- Are humans free to believe in God?
