Man Can Survive a Major Disaster
If there is a major world disaster will Mankind survive? In the past our forebears got through environmental difficulties, so there is no reason to believe that this will not continue to happen. As technology becomes increasingly specialized, things we take for granted will be lost. Humanity will take a few steps back or fall right back into a survival-type culture.
The skill to print could end. Story telling could return as a way to pass on culture. Man has always been inquisitive about what lies over the horizon. Experimentation will still be the key to survival. In a major disaster only those species that can adapt will live through it.
Neanderthals were not smart enough to survive. This is despite their brains being larger than humans. The brains of Man obviously operated differently. This could have been the power of imagination. Neanderthals learned more by direct copying of behavior. Humans can deduce answers from information.
Another important factor is present in humans. We have the ability to live in close proximity to each other. Living in cities is a feature of Man. Neanderthals only existed in small groups. They could not "pool" knowledge and make it available to everyone. We develop and control our environment. Neanderthals did not.
History
City Spiders Are Larger
Many animals do better when they live alongside humans. One seldom thinks of spiders though. If you travel overseas you soon discover the huge spiders in rented accommodation. Research has shown that these frightening but usually friendly creatures do grow larger in warm homes.
They don't have to be living inside the houses either. Just staying close to warm building is sufficient. The golden orb spider was placed in particular external environment and data were collected. Those near buildings were larger and fatter than their bush cousins. Living in the middle of a car park with the heat given off by cars made them bigger as well.
Though many people fear them, urban spiders are harmless. They keep pest insects in check. If they weren't there, we would probably be "eaten alive" by flies and gnats. Rather than spraying and crushing them, put them outside and send them on their way.

Humans Did Not Kill Off Megafauna
During the Middle-Late Pleistocene, one million to 10,000 years ago, more than 50 species of animal disappeared, the last to do so 46.4 thousand years from the present. The reason for the demise of the giant creatures is hotly debated. Some scientists claim that the spread of Man across the globe was the cause. This is suspect, however, because there were so few of them. Killing the odd animal would not have made a significant impact.
Many believe that the end date for megafauna is incorrect. As stated above, the theory that humans killed them off by definition means that people and animals lived side-by-side for a considerable time. Evidence in Australia certainly points to this - 13 species of large animals were here on human arrival. Moreover, the people mainly relied on subsistence strategies for food. Their weapons were not very efficient. A boomerang is highly inaccurate and the range of a spear is limited.
Megafauna died out over a long period of time, not all at a specific date. Species lingered on in many regions. Just assuming that humans killed them is a mistake and diverts from the discovery of why the large animals became extinct. This was a time of extremes in climate. Perhaps a series of wild swings in climate gradually reduced their number to the tipping point where reproduction did not take place.

Less Atractive Males Make do With Plainer Females
An audience affects the behavior of mating male fish. If a male Atlantic Molly (Poecilia mexicana) is left alone he will try to mate with the healthiest looking female - the best female in his eyes. If there are other males in the vicinity he will not choose this female.
It may be thought that he is giving up. This is not the case. He is thinking strategically. By choosing a less desirable female he leads other males away from the intended target best female. The male hopes to mate with this female later when the other rival males have gone.
Some males are just too ordinary and have to mate with lesser females because other fitter males stop them getting close to "ideal" females. Mating with any female is better than not mating at all.
This behavior could be present in humans. When a group of young men meet with a group of young females the handsomest men can be expected to pair off with the prettiest young ladies. The less attractive have to make do with second best. This means that some of the good genes carried by the plainer individuals can be passed on despite mating between the healthier, fitter thus better looking people being the norm.
