Good, hard science. Refreshing & fascinating.

But it's a shame that the event 900k years ago didn't clear all of the progressivism from the gene pool.

Our own 'bottleneck' is sure to come.

Maybe it was climate change....too much fossil fuel being used.

“ The population of breeding individuals was reduced to just 1,280 and didn’t expand again for another 117,000 years.”

That is ridiculous. There is no way that information is known.

First, it wasn't THAT long ago

Second, it was a flood.

Third, there will be another judgement - by FIRE!

“About 98.7% of human ancestors were lost,”

They refused to stop and ask for directions.

This is complete, absolute, unadulterated bull shit. There is just no way anyone on the face of this Earth could possibly state with any accuracy that there were just 1,280 breeding individuals 900,000 years ago.

It’s sad, just sad how science has become fictionalized erratic propaganda. Much of it for political purposes. Much of this has happened since the leftists of the world took over the western culture.

In the past hundred years or so there have been great strides made in the advancement of aviation, medicine, transportation, electronics, just to name a few. If science had always been a joke such as this article, we’d still be traveling by horse, there’d be no airplanes, radios and we’d be using witch doctors for medicine.

Sorry for the rant, but this level of BS ticks me off.

“That is ridiculous. There is no way that information is known.”

Scientists these days are “smaatttt”. They know the weather every day in every location on the planet for the last million years.

next they are going to say that they were socialists, and that socialism saved the human race

I had read earlier the notion that there had been a severe bottleneck in the distant past, but not that they thought the entire human population was that low.

Supposedly a group of 25 chimpanzees will have more variation in their DNA than the entire human race has, because of that bottleneck.

Because each of us is the product of a unique combination of matings between myriads of ancestors over thousands of generations, if that massive die-off had not occurred, none of us would be here now, because other pairings of men and women (from the other 98.7%) would have produced different children who would have different descendants alive now.

Well, they were illiterate, so they couldn't read the road signs.

We call it ‘the great flood’

The critique in this thread is interesting, and expected. I agree with your comment, however.

I've been following genomics for a number of years and the science behind these studies appears sound, entirely dependent upon the power of the processors performing the number crunching. However, as with all aspects of such simulations, GIGO applies, and I cannot deny a GIGO aspect to this study. As well, there are glaring gaps in data which may never be filled.

The 'great flood' was extinction #2, IMHO.

We are now at the precipice of #3. The part of my comment that I chose not to assign to the OP was speculation about how our era might be viewed by those 900k in the future.

Architects of our own demise.
