John Connellan,
There have even been theories explaining the massive incidence of homocide by step-parents of step-children
Were the results supporting these theories expressed in percents? That kind of statistcs may be misleading sometimes. For example: In my country, maternal death at childbirth can jump or fall for several hundred % from one year to another. Devastating statistics? Not really, if you consider the actual numbers: in a year, between 1 and 5 women die at childbirth. One year, only one may die, another year three. Did the death rate rise for 200 %? According to statistics yes, but if the numerus is so small, % statistics become misleading.
Could something like that be the case with the above-mentioned theories?
... our reluctance to devote attention to children not of our own.
But this is natural, I think. Blood ties.
Strange or not, I don't pet other cats or dogs, just our cat.
Lions will also kill cubs of other male lions before they start mating.
Lion society is NOT the same as human!! I mean, in a lion society you have a dominant male who mates with all the females, and you don't have that in humans, do you?!
Also, there are other species that know surrogat parenting, like dolphins, merkats, some apes, even sea-otters. Clue: offspring is not numerous in these species, so they have to care for all the offspring they have. Maybe that was once the original impulse in humans.
Whether males kill other offspring is probably tightly linked to the kind of social organisation those animals live in.
So: you can have less offspring and surrogat parenting; or more offspring and no surrogat parenting. The result is pretty much the same though, in both cases the species survives.
Humans just got things messed up in the process of developing as a society.
Also, another second-thought on the above mentioned theories: Do they show that homicide of step-children in specific for a certain social group, like the poor or something like that?
OK I knew u were going to say this but I dodn't want to tell u too much too soon! U are indeed inadvertently helping the species by caring for others but Im afraid this is not how evolution works. U should definitely read the book the selfish gene.
I think I understand at least a part of your point. Yes, my thinking is likely to be slanted in an environmental way when it comes to humans. There are few animals who kill for fun, many humans find it normal. Look what humans have done with this planet! It is a crying shame.
What I am saying is that if you are destroying the environment you are living in, your species is going to become extinct in the long run. You will die, and the species will die.
Genes may be selfish, but the way human reason is interpreting this selfishness leads mankind into destruction.
You name me one animal that reproduces to a range that the environment cannot support it anymore!!
Can you?
Lemmings have a self-regulative mechanism, hares, if they become too many, get hunted by other predator animals, who then, when the hares run out, die of starvation -- there are regulative mechanisms in nature that ensure Natural Selection, there is always balance in nature.
But humans started playing god and meddled into this process -- that they cannot handle! Human technology is just a try to postpone the inevitable.
Think for a moment about how exactly evolution (through Natural Selection) works and then u will realise why it cannot work in the way u state.
IMO, in human society, evolution and Natural Selection take on somewhat different *shapes* from those in the animal kingdom. The principles may be the same. But I think that the human need to procreate is not so much important anymore as it may have been millions of years back. The Earth is already overpopulated, and if humans as a species want to survive, birthrates must drop, or the environment will not be able to supply our existence. Exactly this is happening in the Western world. People cannot afford to have 10 children anymore, because there are not able to take care for so many, unemployment rises.
Right now, humans are trying to figure out how much is too much. It just that you learn how much is too much only after it is already too much.
I know that I am being emotional about this whole thing, but it just makes me damn angry to see those creatures on two legs claiming to have a reason and to be the "crown of Creation", and doing all the damage they do. Maybe we are the crown: the thing you put on in the end.
