You can see why I might have a little bit of trouble with the reliability of these sources.
Okay. Fair enough. I thought you were making a blanket statement about all the examples rather than just some.
Code:
You have proposed that simply “helping” any group, even other species, is so predominant that it will increase survivability.
Not quite. I don’t think altruism perpetuates itself in humans today. I think it’s irrelevant to the survival of homo sapiens today. This is because homo sapiens have zero trouble reproducing. My argument is this:
A) altruism is an evolutionary advantage in small groups because it increases the odds that the group will survive and thus the trait–since group members, 100,000 or whatever years ago, were all carrying the same genes.
B) In the small group, there was no need to distinguish in-group from out-group because that was handled by fear of “others.” Thus, your genes don’t know for *whom *altruism is for, only that the carrier of the genes is altruistic toward others. de facto, altruism was for carriers of the same genetics in 99.9 percent of cases.
C) Today, we no longer live in small groups, but we are all still altruistic. This is because our genes can’t tell one person from the next and we typically treat more people as our in-group (e.g., people from our town are like us; people from our country are like us; people from our religious or other group are like us, etc.).
So, it’s not that helping just anyone increases survivability. It’s that when altruism would have evolved (based on the chimp evidence, it would be at least several million years ago), the only others we would have sacrificed for would have been related.
They sometimes kill one another. Even human beings do this, as the crimes against humanity in Dafur illustrate so graffically.
That humans kill each other (or chimps) doesn’t mean altruism isn’t present and a consequence of genetics. As I’ve said several times, though, it’s the immorality that really needs explaining–what makes humans kill humans? When people hate other people, they’re more likely to kill them. When people see other people as part of the in-group, they’re more likely to be altruistic toward them. Since all people are essentially the same, the distinction between in-group and out-group is a product of socialization and not genetics. So it is with the chimps, as well. That’s why chimps will be altruistic to humans if raised by humans.
The theory that simply “helping” any group, even other species, is a viable evolutionary and survivability strategy is contrary to experience and is not what is proposed by the article.
But that’s not the argument I proposed, as I explained above.
You can propose a mixed theory, but it by necessity will need to explain how those behaviors increase survivability, unless you want to propose a new theory that leaves out survivability and genetic propagation as a basis.
Again, it increases survivability of the gene because the altruistic behavior, in nature, virtually always targets a closely related individual. If humans or chimps evolved in mixed groups (like living in modern cities, where most people you see are *not *related to you), I’d have to agree with your point. But, they evolved in groups of more or less close kin.
You can appeal to the “mistake theory.” Again, there is a major problem here giving any explanatory power to this as evolutionary stable behavior. Mistakes that do not lead to survivability are not traits expected to be passed on. It is also ironic that mistaken behavior is the only behavior that is deemed altruistic. You need to explain why we would expect this mistaken behavior to continue if it does not promote survival.
It continues because everyone has the trait–thus, if any one human survives to reproduce, the trait would almost definitely be passed on.
But, I agree with your general point. I agree that in humans today, it’s not stable. Since it’s irrelevant to survival in humans today (so I argue), it will whither away, and humans, so long as they live in mixed groups, will become decreasingly altruistic. As I said in a previous post, though, humans have only lived in mixed settings for a very brief period of time–not nearly long enough to have such a severe impact on the general population’s genetic make up. My guess is that humans will kill themselves off before evolution kills them off by taking away their morality/altruism. It’s another “mistake” that humans’ “genius” is allowing them to destroy the environment without which they cannot live.
Human beings haven’t always exhibited this behavior, much less other animals. This is self-evident to those of us who watch animals savage one other everyday, including humans. All you can really conclude is that human beings have sometimes exhibited this behavior.
Humans probably have always exhibited it. What changes is the definition of the in-group and out-group–which is social rather than genetic, and genes don’t know the difference. That’s the key. We’ve only *not *lived in small groups for a very short period of human history (seriously short–less than 2 percent of the time modern humans have been around, if I’m being generous to your argument). That’s not enough time for the “mistake” to cancel itself out. Chimps, on the other hand, still live in a state of nature–they’re not going to lose it. We can pluck them out of their troupes all day long and raise them with humans and they will be altruistic toward humans, because their genes don’t know the difference. So long as humans (like Gates) don’t see others as a threat, that drive to help will prevail.
