Going extinct may not be as easy as we imagine

If you thinking in one disaster only, it wouldn't be as easy as we think to erase the Human totally.

Who says it will only be one disaster- If we look at our religious books they describe several disaster after each other. Even here there will be survivors among the humans.

There's one disaster in which there will be no survivor-That is if we haven't started to expand our livings to other planets. What I'm talking about is when the sun grow and eat earth.

Another question is.

What about our own development? Right now we are called Homo Sapiens Sapiens. How would the next step be like ? And would they outrun the Homo Sapiens Sapiens or will there be survivors ?
Even here-When the first Homo Sapiens came they almost erased the Neanderthal from existing. From what I remember they lived among the Homo Sapiens for thousands of years before they finally got extinct.

I’m not so sure extinction is such a good choice to describe what happened to Neanderthals. Especially since some Homo sapiens carry Neanderthal DNA. Might better to say they were eventually bred out between 100,000 and 350,000 years ago.

As for extinction events like asteroids striking earth. Its the few hunter gathers left in the world who most likely will survive and carry on. Those who only know modern conveniences will be the first to go.

Plus they likely got outsmarted. Nutrition science and anthropology say that modern man lived in coastal regions or near rivers and had access to omega-3 fatty acid-enriched foods that made them more clever by growing their brains, while the Neanderthals had not, not to that degree at least. With that came greater intellectual adaptability to the challenges of life that saw Neanderthals more often loosing, compared to homo sapiens.

Our brains have shrunk again meanwhile, too, loosing - if I recall the numbers correctly - around 12% in size/volume over the past I think 15 thousand years or so. With the agricultural revolution 14 thousand years ago began the rise of settlement building and cultural development - at the cost of a general physical degeneration setting in. Skeleton, bone density, jawbone size, stamina, immunity and resilience to desease, brain size - it all declined. Modern Western industrially prcessed foods and carbohydrate-rich food add another acceleration to this degenerative process.

Another factor was climante chnage (:LOL), and that Neaderthals simpy followed their animal foods into the colder regions, because their preferred preys did not like warm climate, but were adapted to the colder climate zones. When the Neanderthals follwoed htem, he moved fiurtehr and further away from potential food alternatives, and when he hhd hunted down all big wildlife, he found himself stranded in regions where food then became scare and hunger started to decimate the Neanderthals.

There are no realistic scenarios in which a single event can eliminate mankind completely.
An alien invasion followed by an eradication campaign might do the trick, but I dare say that's not within the scope of "realistic"

From the article:

From the genetic diversity of our genome today, scientists have been able to reconstruct that the number of our ancestors fell to just over a thousand individuals 900,000 years ago. The cold and drought probably caused the community to shrink to the size of Kandersteg. It must have been hard times, at any rate the number of our ancestors hardly grew over the next 5000 generations. Only after 117,000 years did they spread out again.

You are right
What I tried to explain is that in the future a new Homo-something will arise and they will live among us, as I mentioned before
The Neanderthal lived side by side with Homo Sapiens until they were instinct. Even though they live in our DNA

Maybe reading Carson's "Silent Spring" might change this opinion
