An exceptional argument. You sound like you're owed something more.

I... Do want to catch crabs?

Yeah, yeah, yeah. And we have to eat meat, and men have to kill things, and everybody has multiple partners.
Also we have evolved to carry around much more fat than we used to, and to  covet things  that are very large and ostentatious.  It's just evolution.

Worried you're carrying that particular gene?  Modern science has developed a simple, fast, and accurate at-home test: Check and see if there's an "R" after your name.

We can all agree tools are very old in our history.
In fact, the multitool is from the 1200s.
But when was the earliest tool belt?

Oftentimes, natural selection isn't of the fittest, only the most vicious.

Not necessarily. Outcompeting can be viciousness, strategy, or just dumb luck.

There's a spiky weed that grows low and short in America. It evolved back when there were rhinoceros type grazers and outlasted the predators. That's viciousness.  Ants have two stomachs, one to digest and one for sharing.  That's a strategy.  Then the humble hot pepper. The chili was going along ok with its spicy, vicious defense. Then along came a dumb ape that liked the feeling of chemical burns in its mouth.  Instead of being grazed to extinction, like many other species this dumb ape has liked, the pepper got propagated and vastly extended its range even as far as space! You can't compete for that kind of thing. That's just everything coming up Milhouse.

In evolutionary biology, fitness is basically defined in terms of the ability to have offspring that can themselves have offspring. Viciousness might result in more kids or less kids depending on the environment. Hell the weaklings will be more fit than the strong if they have more kids. An example of this is if the weaker organism is more attractive to the opposite sex. (We are also assuming that it is cause of traits is at least partially genetic as natural selection acts on genetic differences.)

I think it's more due to living in a hyper competitive capitalist society that sadly rewards sociopathic behavior. But maybe that is just a natural outcome of being predators. Sad really.

Look, if everyone would just shut up and listen to me: I'll take all the food and divey it out. Okay???

The chromosome may contain regions that promote their DNA's spread by killing sperm that carry Y chromosomes. However, Y chromosomes may have evolved counter mechanisms over time

So the sperm are battling it out in my testes?

No wonder my balls ache.

The research is about a gene that is "selfish" in the sense that it propagates itself to the next generation very well even though the result is not necessarily good for the individual or the species as a whole. It is related to the concept of "gene drive".

It has nothing at all to do with the individual themselves being selfish.

By the way, can you tell that nobody else in this thread read the article, including subby?

Capitalists are predatores.

Humans have to figure out a way to oversee this primative expression with democratic institutional power........

A democratic socialism or social capitalism system is the only one with a long term chance of success.

But self centered capitalist pigs own all the news networks and advertising media so they make sure people like noam chomsky and bernie sanders are ignored.

Divided we fall

United we stand.

The big business owned news media makes sure that we are divided and conquered.
