What's this whole genetic diversity bullcrap?

[Pray To Jesus]

I don't buy it at all.

I don't buy it at all.

not sure if serious

Please eliminate yourself from the gene pool then. Thanks in advance!

:awe:

Genetic diversity refers to both the vast numbers of different species as well as the diversity within a species. The greater the genetic diversity within a species, the greater that species' chances of long-term survival. This is because negative traits (such as inherited diseases) become widespread within a population when that population is left to reproduce only with its own members.

yeah, i found that one too SKORPI0, and decided against it :whiste:

 

[busydude]

STFU you inbred buffoon.

 

[yhelothar]

At first I was like... WTF?!
but then I saw the OP's username...
and I lol'ed

According to the THEORY of evolution: All the ones with negative traits die off leaving only superior traits in the future.

According to the THEORY of evolution: All the ones with negative traits die off leaving only superior traits in the future.

According to the extremely well-evidenced theory of evolution, life forms with negative traits that result in a survival disadvantage are more likely to die off at some point in time.

You can get life forms with all kinds of useless traits and useless genes. If they don't put it at a disadvantage, then there's no pressure from any direction for the genes responsible to go away.

you're not supposed to buy it. it get's shoved down your throat for free.

First, you seem to misunderstand the word "theory" in the scientific context.

In modern contexts, while theories in the arts and philosophy may address ideas and empirical phenomena which are not easily measurable, in modern science the term "theory", or "scientific theory" is generally understood to refer to a proposed explanation of empirical phenomena, made in a way consistent with scientific method. Such theories are preferably described in such a way that any scientist in the field is in a position to understand and either provide empirical support ("verify") or empirically contradict ("falsify") it. In this modern scientific context the distinction between theory and practice corresponds roughly to the distinction between theoretical science and technology or applied science.

A common distinction made in science is between theories and hypotheses. Hypotheses are individual empirically testable conjectures; while theories are collections of hypotheses that are logically linked together into a coherent explanation of some aspect of reality and which have individually or jointly received some empirical support.

Second, evolution happens over the course of time spans that are difficult to comprehend. If negative traits are too widespread within a population, ie: the genetic diversity is low, you are correct - the species in question has less of a chance to survive on a large timescale without the introduction of new genes that overcome the negative traits. Understand that "evolution" the way you're twisting it doesn't happen over just a few generations. If too many individuals with negative traits die off, genetic diversity is lowered even more, further reducing the chances of species survival. It's almost as if you think things haven't gone extinct naturally.

Third, trolololololol.

So why don't trolls like you die off?

 

[PieIsAwesome]

but is jsut a theory derp!1!1

 

[HamburgerBoy]

tbh I think a lot of people do exaggerate the negative consequences of incestuous breeding.

 

[Modelworks]

Read up on the kings and queens in history, that is what happens with little genetic diversity.

not that there is anything wrong with that (anymore)
