It doesn’t. Lenski’s bacteria evolved to digest citrate when oxygen was present (which they couldn’t do before) in a few years. Some changes take a long time, others can occur much more quickly.

Adaptation. As you pointed out they had the ability to digest citrate already.

Yes, so…if they weren’t human like someone said, then are we partially not human?

But Adam and Eve probably didn’t know one another.

That is what they say. If one has followed the science, they first said they were hundreds of thousands of years apart. Now they are saying they lived at the same time. Next thing ya know - …

In the last few decades science and archaeology have actually supported Scripture more and more. The confidence factor is increasing.

Adam and Eve DID live in Africa at the same time

Well, not quite.
  • 'Y-chromosomal Adam’ is thought to have walked the Earth between 120,000 and 156,000 years ago
  • This places him nearer to Eve who was around 99,000 to 148,000 years ago
  • Researchers say it is ‘extremely unlikely’ they were exact contemporaries

That is to say within a span of 57,000 years. Not my idea of “at the same time”.

How could we interbreed if they weren’t human, or, more importantly, do humans have parts of non human blood coursing through our veins?

Humans and Neanderthals did interbreed but I read somewhere that there is evidence that some of the offspring were probably infertile. This is perhaps similar to the way that the offspring of a horse and a donkey is infertile, i.e., a mule. The two have a common ancestor in the distant past which is close enough to allow offspring, but distant enough that there are complications.
 
Neanderthals were fully human. As time passed, artists’ renderings changed from this brutish guy to something much closer to modern humans. If you examine the skull shapes of the various races of humans alive today, you’ll see a wide range of variation. Neanderthals were a racial type.

From Sanford’s paper:

Together, these various genetic mechanisms seem to falsify the claim that there is “no way” that two people could give rise to the human allele distribution that we see today.

Sanford does not give a timeline here. Those two people would have had to have lived between 500,000 and 7,000,000 years ago. That is before Homo sapiens evolved about 250,000 years ago.

Sanford’s Adam and Eve were not of our species.

I note that you do not have any of either Adam or Eve’s DNA to test. Hence your claims about their genetics are scientifically unsupported.

Adaptation is evolution. I showed that an evolutionary change does not have to take “million of years”. Evolution can work a lot faster than that.

Probably more similar to tigers and lions interbreeding, where male crossbreeds are sterile while female crossbreeds are fertile. That would allow some cross-transfer of DNA, but not very efficiently.

Neanderthals were not simply a “racial type”. The Neanderthal genome has been sequenced and it has significant differences from the genome of modern humans. And physiologicaly, there were some important differences.

You missed a big point in that they were designed.
