Turns Out, Human Ancestor Almost Went Extinct 900,000 Years Ago

For those who have heard about the genetic bottle neck humans experienced long ago where as a species we almost went extinct here is some more studies about the subject. Ice age and a very low number of breeding pairs world wide.

Today there are over 8 billion humans living on our planet. However, if we had looked at the world between 800,000 and 900,000 years ago, the picture would have been shockingly different. New scientific findings shed new light on our ancestors, and point to an important human speciation event. Indeed, Scientists are only now shedding light on a previously unknown period in human evolutionary history. According to a new study, early humans known as 'Homo erectus' nearly went extinct less than 1 million years ago, likely due to extreme ice age conditions. According to genetic evidence, between 813,000 and 930,000 years ago, modern humans' ancestors experienced a severe bottleneck losing approximately 98.7% of their breeding population. Remarkably, our forefathers faced extinction due to a severe population bottleneck that lasted for a heck of a bloody long time. In fact, our ancestors' estimated population size was so small, they would almost certainly have gone extinct if not for shear determination and dumb luck. A study, titled 'Genomic inference of a severe human bottleneck during the Early to Middle Pleistocene transition', demonstrates this fact. The evidence shows that The human population remaining very small, but stable for more than 100,000 years, also fueled the divergence of modern humans, Neanderthals and the so-called Denisovans.

We are a bunch of horny hominids .

Why haven't the apes over run the planet by now ?

Much of this 'talk' is anything other than scientific. Yeah ... it's okay (I guess) to call it a theory, but when it's wild-assed guesses ... and people won't openly state that ... then I have to say the "s" in science is headed towards an "S" in Science. If it's 'just' Ice Age ... one has to recognize that the whole of the land is not frozen over. That there are still seasons and green things grow year after year. So, what are they going on about here? Snowball Earth?

You can pretty much rest assured that when Snowball Earth happens (and it 'probably' does), everything on the surface of the Earth perishes. Probably some things that can survive being frozen (like plant seeds) could wait it out. But, the stronger likelihood is that anything appearing on the surface after ... would have had to have lived it out underground for probably ten of thousands of years.

What does that mean? Our ancestors are probably living inside the Earth because they were technically advanced enough to do that. Why is it that we're out here instead of underground with them? Maybe (like Australia) we got kicked out because we were bad. Rogues from the underworld. LOLOL Just because they're underground every single day, doesn't mean they don't have the technology to get out here and fly around. Maybe they're just happy in there and mostly don't wanna come out and see what's going on.

The other thing is speciation. Science has yet to account for all of that. Is it possible that after a deep freeze that anything that can survive through Snowball Earth gets a good old fashioned irradiation treatment? The projected/speculated orbit of the Earth takes us closer to the Sun. That "can't be good" for our DNA. You know it's hard to tell from shape alone what a lifeform's end-state will be. Imagine solar radiation hammering the Earth for tens of thousands of years. Not enough to necessarily kill ... but enough to force transformations/mutations during early stages of growth.
