You already explained why tho, as many animals are born being capable of surviving already. Humans are so under developed at birth they rely on both parents to ensure the best possible chance of survival.

Basically pretty much everything can be explained by science and biology.

There was an amazing nature documentary on BBC 2 and they actually exist in the animal kingdom, using sneaky tactics to reproduce aswell.

So some examples, most females are guarded by the alpha male while they're fertile, cuttlefish runts will use camouflage To change their colouring to that of a female, sneak under the alpha and quickly mate before running. Beta beetles will dig their own tunnel leading them to the female, mate and run away. The runt moose while chase the female while the alpha is guarding her and use speed to mate mid sprint before running away.

If they included humans they would of used a male championing female rights before befriending them.

Of course but it's not so much as the wealth women are attracted to, it's the traits of a wealthy man, a wealthy man will usually be ambitious, intelligent, driven ect and the fact they can be the best possible provider. We refer to women as gold diggers but there's actually nothing wrong with that, it's what they are naturally programmed to do. We would never evolve as species if women were attracted to men that couldn't protect or provide for them.

Revert back to society that isn't under a monetary system and the rich and successful guys would be replaced by the best hunter gatherers.

The only difference now are the best in society get rewarded by money and are able to preserve and pass down their wealth, so you will get useless humans who hold high social status and are wealthy who would never have been capable of achieving this on their own merit.

If you do anything remotely unselfish now for someone you believe to be in need, you're accused of 'virtue signalling' or of having some unseemly motive, depending on who you are helping.

It's no doubt a very comforting life to have that mindset, because you get to perpetually talk yourself out of bothering to be a decent person towards others.

Actually have one female friend who have known for many years. Both married and get on really well but no 'physical' interest in each other. Meet up every so often and chat about all and everything.
Unusual I admit -but really enjoyable.

Not really true, hunter gathers tend not to be the most respected members of tribal society, as they fulfill common roles of non-specialists (the unskilled labour) are traditionally lower class than specialists in those societies.

Being capable of build houses, manfacturing clothing, digging wells, raising animals for tanning leather, extracting metal and making weapons, tools and production of food and religious ceremonies coverts much more prestige in primitive societies. Tribal societies don't tend to be led by the best hunter or gatherer - but almost every male will start out as a hunter-gatherer. Leaders of tribes tend more towards the thinkers and planners, rather than those who are 'stuck in the job they got after leaving school'.

If you're a hunter and a gatherer, as an adult, you're not really very successful. Its a useful skill but your not cutting it as a man. Its more like an entry level job - As people get older, they do less of it and more often socially, rather than functionally.

It was farmers, that transcended Hunter Gathering societies, not the bold hardy hunter who could fetch food and hunt down prey (thats what you do if you can't do anything else). Human society has a long standing tradition of rewarding those who think, over those that do.

No society has ever really rewarded the disposable labour force - and that is what being a hunter and gatherer in a tribal society is - The disposable labour.
