When 'good genes' go bad: How sexual conflict can cause population collapse
phys.org ^ | 03/05/2023

Posted on 03/05/2023 6:05:25 AM PST by devane617

Males of a species evolving traits for sexual conflict can cause problems for females, and, ultimately, the whole population.

A new model by Imperial College London and University of Lausanne researchers, published in Proceedings of the National Academy of Sciences, shows how so-called 'good genes' can sometimes cause a population to collapse.

Males of any species may compete for females, either by fighting other males for access or impressing females to win their approval. In both cases, males expressing the most competitive traits—such as the best ornaments, like peacock feathers, or the best weapons, like big body size—access more females.

To have the best traits the males must be in good condition, for example to be in better shape or carry less disease. Over time, as better-condition males mate with more females, the prevalence of 'good genes' increases throughout the population of the animal, leading to the population as a whole to improve in condition.

However, it can also backfire. Traits than improve a male's competitive prowess can also damage females. For example, some insect males have evolved penises that tear the females' insides, and in many species, including mammals, males have evolved to harass females to induce mating. These behaviors reduce female fecundity or may even kill them.

“…new model by Imperial College London and University of Lausanne researchers,…”

Where once the above may have recommended the reading, this, for me, is no longer true. Quite the opposite actually. I simply wonder what political bullshit they’re trying to pass off now. Wish I were exaggerating even slightly.

Wasn’t it “Imperial College London” who provided the first terrifying, outrageous, and ultimately totally untrue estimates of covid fatalities used by the West to justify lock-downs in March 2020?

“Considering that we are logical and rational...”

LOL. That’s funny.

Notice in all these articles it is always the male who needs to be fixed, never the females.

No agenda there...

Considering that we are logical and rational and not just acting on instinct in that area of life?

Logic and rationality lie on the far side of an erection.

Okay. Now do "females who kill the male after mating with him."

Not only that.

Reverse Bestiality: When Animals Commit Sexual Assault

By cwilcox on January 27, 2011.

Sexual assault is no laughing matter - unless, of course, the would-be rapist isn't human. Who doesn't giggle when they see a small dog humping someone's leg? But what many people don't realize is that reverse bestiality - where an animal makes unwanted sexual advances on a person - is a true problem for scientists working in the field where the actions of wild animals are completely unpredictable.

so-called 'good genes'

Hmmm, wonder what the consequences of the Covid 19 Gene Therapy might be. Think about it.

What IF?

If in fact 70% of the population of the world is vaccinated,

and if in fact the mRNA treatment not only kills some right after they are shot and others long aftger, and if in fact the body of the rest receiving it somehow reverse transcribe to the DNA,

and if in fact it is transmissible to the next generation, and if in fact it reduces procreation by increasing miss carriage?

Where does that leave the human race

I am not saying that is all true, but there are some knowledgeable who think it might be possible.

Is this in fact not a Nuclear Bomb but a Genetic Bomb?

Ooh, “good genes”. Umm, any hint on whether this applies to Jews?

Gimmie a F**ing break.

Another anti-male screed.

I’m usually a civilized person, but a part of me wants to just flatten these morons...and I’m a woman!

The issue is NOT the virus.

The issue is the mRNA gene therapy and it’s consequences.

They lied to us from the beginning, they will not stop lying to us until we remove them from power or otherwise neutralize their influence.

Many of them should go to jail for what they have done.

Trump knows it.

25% of the USA knows it.

Another 25% knows it but is somehow complicit.

That leaves 50% who need educated in the truth.

Yes

These are crimes against humanity.

And a heavy dose of Treason to the USA intermixed with it.

Yeah, I thought that too at first. Then I read the full article and saw they were talking about insects and other non-human animals.

Just wait, they will try to correlate it somehow with humans in the future.
