Science We Are Evolving....?

[wizenheimer]

yeah, I know human evolution seems counter-intuitive as we watch trump and his base leave no rock un-turned in their mad race to non-intelligence.....

but apparently, we are adding arteries and losing wisdom teeth:

and:

the drawback to this, for lengthy guys like me, is that shorter-jawed women would limit my love life, if you know what I mean....(insert endless jokes here)

 

[yankeesince59]

Makes sense to me...the appendix is gradually disappearing over years of evolution and I'm sure there are other instances.

As to your concern about "short jawed" women, does that mean that one day all females will have overbites?...oh, the humanity, glad I won't be around.

 

[riverman]

I sure hope so, but there is a contingency amongst humans that I think is moving the opposite direction....probably from inbreeding or Neanderthal dna! Problem is intellectually we seem to progress but emotionally we can be pretty barbaric

 

[crandc]

Of course we are evolving. All species are.

LINK?

THE MISSING..........

LINK?

 

[crandc]

Link? That is biology 101. Species aren't static. Some, like viruses and bacteria, with short generation times, evolve so rapidly we can see it. Others, with low reproduction and long generation, take longer.

The one constant in the universe is change.

Your going to have to prove this magic you speak of...... I'm as good looking and fit as I was yesterday. #GoTrump

 

[riverman]

Pretty sure my children and grandchildren are smarter and better looking than I ever was so that's a good sign.

 

[julius]

Sure, a majority of us evolve...and the rest vote for Trump

Your brains and looks are setting an extremely low bar for those to overcome.....but whatever FAMS!

 

[SlyPokerDog]

I'm proof that dogs are evolving faster than cats.

Yes, they're adapting to their lives as suck-ups to humans. Most are becoming wiener dogs.

 

[e_blazer]

I've read that there's considerable discussion about how the rise of human technology and agriculture has disrupted the typical stressors of nature so that we aren't evolving through natural selection nearly as much as in early human history.

I do try to make it easier on the next generation!

That's only because cats move faster and quieter than dogs can sense.....probably one running around your tail right this moment

Correct. Dogs and wolves are so genetically close they can interbreed. But when dogs were domesticated, they were selected for docility and obedience. In consequence their jaws became smaller and they lost intelligence. Wolves regularly beat dogs in tests of intelligence.

Cats, although domesticated, retain most of their wild instincts and are much closer in intelligence and appearance to their wild counterparts.

I find great pleasure in witnessing how this forum has evolved ever since SPD became our Grand Poobah.

Cats let you think you've domesticated them

 

[crandc]

Cats let you think you've domesticated them

It's the opposite of course.

 

[ABM]

It's the opposite of course.

As an aside, have you seen this?

 

[crandc]

He wanted to shoot that beautiful cat. Creep.

 

[Lanny]

Of course we are evolving. All species are.

Yeah, but it's almost as slow as watching grass grow or paint dry. Fortunately, Trump and his cronies winning the Darwin awards year after year after year occurs with much much greater frequency and that is fun if not incredibly painful to watch.

If wolves are so smart, why do they eat cats?

 

[crandc]

Wolves are predators. Cats not regular diet but predators hunt what is available.

Archeological evidence shows cats essentially domesticated themselves. When humans began semi settled communities, that meant food storage, which meant rodents. Also garbage dumps for bones and other scraps. Cats were given access to a rich food source. The wild cats who ventured among a strange species self selected as most adaptable individuals.

Cats are unusual in that most predators hunt until their stomachs are full, then stop, but cats continue killing prey even when no longer hungry. This is why they are so valuable for rodent control, and conversely, so destructive to birds.

 

[Chris Craig]

I think some of us may be de-evolving

I certainly wouldn't say that he wanted to shoot the cat, but if it were to charge at him? I love animals as much as anyone, but I'm not in favor of becoming cat food.
