Evolution 101:
.
This is one big reply to several posters:
.
Alright, I came here to discuss metaphysics. I didn’t come here to explain and advocate natural selection to evolution-deniers, or to justify science to science-haters.
.
Besides, I suspect that the evolution-deniers and science-haters aren’t really that, and are just devil’s-advocate-trolling.
.
But here I am anyway, replying in this topic. Explain
that.
:)
.
.
And we've now reached a point where natural selection pretty much no longer applies to humans. The 'weak' humans end up being raised into adulthood, with just as much opportunity to reproduce as the 'strong' ones. Unless we start picking and choosing who can have children, I don't foresee any further advancement of our physical and mental abilities.
.
Maybe, but if eugenics conflicts with kindness and humanity, I’d choose kindness and humanity.
.
But don’t expect societal improvement.
.
What has been the result, the culmination, of all of the best efforts of people working for societal improvement? Don’t take my word for it, just look around at what’s happening societally.
.
Have you ever noticed that the sheep are matched and suited to their herders like a glove to a hand?
.
…as if the sheep were
made for their owners?
.
It’s like Huxley’s
Brave New World, except that of course there’s nothing new about it. And of course, in real life, as opposed to the novel, it wasn’t achieved by drugs.
.
It was the result of evolution.
,
Don’t get me wrong. It’s amazing what evolution has accomplished. If you aren’t awed by it, then you haven’t noticed it.
.
But there must have been a time in our species’ prehistoric past (and after too?) when complete obedience to authority was adaptive.
.
Think of it as a “theory” to explain societal events and the societal stasis.
.
It’s a particularly well-confirmed theory.
.
P.T. Barnum said that there’s a sucker born every minute.
.
W.C. Fields said, “Never give a sucker an even break.”
.
Those two great social-scientists have provided the explanation for the societal stasis.
.
It can be called a stasis, because of course nothing has changed throughout history, from ancient times, to Classical times, to medieval times, renaissance, up to modern times. Only a few details of the herding-method, the mode, have changed, with technological advances.
.
I don't understand how natural selection can select something if it doesn't already exist. Hence we are left with the issue of how these emergent properties come to exist.
.
There were always differences and variation among individuals. Those differences were augmented by mutations. Most mutations were maladaptive. But just a few were adaptive. The individuals with those adaptive mutations (or just with more adaptive attributes within ordinary variation) survived long enough to pass them on. Soon the individuals with the more adaptive traits and attributes increased their percentage of the population.
.
That’s how varieties of species arise.
.
As industrialization arrived, in some places soot filled the air, and trees’ bark became blackened with soot. In at least one location, it was noticed that the moths that landed on the tree-bark had eventually acquired a dark coloring, for camouflage against the black tree-bark.
.
Sometimes populations become geographically separated for one of any number of reasons. Maybe some move into a new niche somewhere else. Then, as the two populations continue to diverge, in their separate adaptation to their different environments—or maybe just because they’re geographically separate and not interbreeding—soon their genetic makeup is so different that they can’t interbreed. …or at least not with the full efficiency that’s possible within a species.
.
Now there are two species instead of one.
.
That was inevitable. That speciation has been happening for as long as there’s been life.
.
People seem to be conflating the benefit of a trait with a causal explanation.
.
The benefit of an adaptive trait results in its possessor surviving longer, having, and successfully rearing more offspring. …resulting in adaptive traits increasing in the population.
.
Causal? You bet.

This is another abuse of "hierarchies"
.
"1920s, Belgian ethnologists analysed (measured skulls, etc.) thousands of Rwandans on analogous racial criteria, such as which would be used later by the Nazis. In 1931, an ethnic identity was officially mandated and administrative documents systematically detailed each person's "ethnicity,". Each Rwandan had an ethnic identity card.[11"
.
These identity cards formed part of the later Genocide.
.
Science (and misunderstandings of science) has been abused. Does anyone believe that abuse of science and technology hasn’t taken place even
after the Nazis?
.
But are we worse off because of science?
.
How were things in medieval times? Sure, rulers didn’t have the technology to do as much harm as they can do now. But they did the best they could, didn’t they. …reminiscent of the Walrus in
Alice in Wonderland (or
Through the Looking-Glass?), who didn’t eat as many of the oysters as the Carpenter did, but nevertheless ate as many as he could.
.
If you lived in ancient times, would you still be alive at your age? And what kind of hardship would your life have consisted of?
.
Yes, arguably, life might have been pretty good in Paleolithic times, but that lifestyle just isn’t societally-attainable now.¬

Since Evolution is indistinguishable from other Western religions…
.
Evolution isn’t a religion. It’s an established fact.
.
…, it would make sense that adherents would draw the same conclusions, e.g. being Gay (or any other target minority group) is unnatural and is a target for extinction.
.
Thoroughgoing utter nonsense (as from a troll).
.
The Nazis abused their misunderstanding of evolution, but that doesn’t mean you have to be an evolution-denier. Most people who aren’t evolution-deniers don’t endorse or support Nazis or the like.
.
In fact, evoluion-deniers are among the most numerous supporters of Nazi-like policies.
.
This the Nazis could justify the murder of tens of millions of people by simply suggesting that they were agents of the natural universe. Similarly, the Inquisition could be justified as the adherents being agents of The Lord.
.
Your conclusion: So we should all be evolution-deniers and science-haters.
.
The Nazis’ misunderstanding of science, and the Inquisition’s decidedly unscientific justification for its crimes have no valid role in justifying evolution-denial or science-hating.
.
We can thus view Evolution and religion as a battle for the hearts and souls of fatalists (determinists) who embrace the concept of an outside force directing the Universe.
.
Too silly to answer. The question is, why do I waste my time answering trolls? Well, just this last post, and that’s all.

“Natural selection suggests that gay-ness must have an environmental component.” — Michael Ossipoff
.
The discussion is about the all-powerful force called Natural Selection which was totally concocted by science
.
Science didn’t concoct evolution; it discovered evolution.
and which seems to be obsessed with reproduction
.
Selective reproduction is the obvious mechanism of evolution.
.
See above in this post, regarding natural-selection..
.
(something Freudian going on here)
Darwin was a few decades before Freud.
.
Freud deserves credit for having the courage, in Victorian times, to mention the dreaded “S-word”.
.
Other than that, I don’t know that Freud said anything societally helpful. (But I’m no Freud-authority.)
.
. Apparently, according to this reproduction obsession, Natural Selection is weeding out all those that aren't equally obsessed.
.
Obsessions probably aren’t optimally adaptive. But yes, natural selection has tended to weed out survival-&-reproduction-disadvantageous attributes.
.
But it isn’t just reproduction. It’s survival for long enough to reproduce and successfully rear and protect one’s offspring.
.
It's all about procreation? Sounds very strange to me.
.
Sorry, but it’s nevertheless true. What, other than selective procreation resulted in speciation?

“And no, the suggestion of an environmental component to gay-ness doesn't feed Nazism. But anti-science advocacy does. “—Michael Ossipoff
If theres an environmental aspect to Gayness that can make one Gay, there has to be one that can make one straight.
.
Of course. But there’s also a blatantly-obvious natural-selection influence too.
.
, but theres neither.
.
That’s your scientific pronouncement? I stated an obvious reason why, in view of natural-selection, a strong environmental influence is needed to explain gay-ness.
Rich:
“And no, the suggestion of an environmental component to gay-ness doesn't feed Nazism. But anti-science advocacy does.” — Michael Ossipoff
.
Nazism was entirely technology driven, and after the war the U.S. used many Nazi for our missile program.
As far as ideology was concerned, the concept of the survival of the fittest race was music to their ears. They actually set up labs that experimented on humans (in the most barbaric ways) trying to figure out ways to exterminated faster. It was all about Natural Selection and the survival of the fittest.
.
Answered above, in this post.
.
Natural selection can only select something after it begins to exist. it can't produce consciousness (or gills) on demand. conscious has to begin to exist before it can be of any use. — Andrew4Handel
.
Adaptive attributes either existed here and there among the population, to varying degrees, or else were the result of (usually maladaptive, but sometimes adaptive) mutations.
.
(see the natural-selection explanation, above in this post)
.
The changes, from one generation to the next could have been quite gradual, but eventually, over time, those changes could be big.
.
Animals react to their environment. Call that “consciousness” if you want.
.
You haven't really proposed any argument apart from telling people watch this etc I have a degree in psychology and philosophy. I know how neurons work and about different brain structures, I know about fMRI etc (I had to write a critical essay on brain scanning techniques) etc and studied the search for neural correlates. I had to read seven books on the philosophy of mind for my course and I have also read Dennets Consciousness explained. — Andrew4Handel
.
Consciousness is used as an obfuscatory way to refer to the fact that animals react to their surroundings.
.
"Consciousness explained"? Darwin explained it in 1854.
.
Sorry, Mr. Dennet.
.
I have proposed an argument - that the mind has evolved as a result of environmental selection pressures and that consciousness improves evolutionary fitness.
.
That’s Darwin’s explanation.
.
He beat you to it in 1854.
.
Heterosexuality is not explained yet it is taken for granted because of it obvious benefits to gene transmission/reproduction. — Andrew4Handel
You say that it isn’t explained, and then you give its obvious explanation.
.Alright, enough troll-engaging, evolution-defending, and science-defending.
.
As I said, I’m at this forum to discuss metaphysics.
