haha virgin

[tigleytummy]

19 secs into the video and an add comes on. what is youtube turning into?

[Blargleflakes]

That bird had tig ol bitties

People in this culture are so afraid of death I think that is the problem.

People do everything in their power to squeeze out a little more time...

For what? So you can watch more Dancing with the Stars?

Death is not the worst thing that can happen.

I feel so bad for the grouse with TB. He'll die alone, but at least he'll be contributing to the betterment of his species by not passing on his bad genes.

1:42  JUST WHAT IS THAT?! O_O

[babiibutt21]

HAPPY FEET!

AWWW the poor peguin at :36

I wish this guy would stop freakin narrating lol

But look what's happened every other time we've intervened in nature. Who thought bringing rabbits to New Zealand was a good idea? Then weasels to control the rabbits. Now the native birds are on the way out because they're mostly flightless having lost the ability to fly because there was no selective pressure to do so. No native mammals. And flying is an "expensive" strategy so it just faded away. Then in come the weasels. POOF! Extinctions everywhere.

Maybe there's a lesson in there....

[lowellriggsiam]

It was just as smart as introducing Mongeese to Hawaii to deal with the rats. The rats are nocturnal and the mongeeese are not. Some form of scientific intelligence went into that.

[warren52nz]

Yeah I think the gene pool will get infected. "Human selection" happens so much faster than natural selection that Evolution is pretty much dead in us. Except for the very fast types like immunity to viruses.

I guess you could argue that medical advances may be able to counter this indefinitely so that genetic defects don't really matter. Eventually they'll be able to correct them too.

[dubaimillionaire]

lol thats funny birds...

[knytebyte]

and i thought blue balls were a drag

[warren52nz]

Natural Selection is dying in humans. I know it's sad & some would say immoral but a lot of babies who survive only because of medical intervention shouldn't. Those that wouldn't have made it because of a genetic defect should be taken out of the population by Natural Selection because if they go on to breed, their defect may be passed on to the next generation.

The only way to stop that would be to ensure they don't breed and that violates human rights. So Natural Selection is fading away...

[VaticanIscariot]

glad someone else agrees xD

[thatsMrSmileytoyou]

It relieves me to finally see a post from someone on the same level. We're breeding sickness and disease back into human genes. Some of these people "want to have their own kids", and go to great lengths to do so but have they even considered adopting? The world's changing, we can't continue this and expect to prosper. We're human beings, we're not devine. Sooner or later the mental and physical potential of our unborn will take its toll on our future as a species. I pray for this planet's soul

[sangohan37]

omgosh you guys are horrible. How could you even thing of discarding another human being as if it were trash. it isn't the babies fault if he is born with an illness, if anyone is to blame it is the parents. this kind of thinking is one step away from someone going out an killing the mentally ill children or handicap. Seriously what kind of morals do you guys follow if any. This is merely an evolutionary arms race, we just have to make sure we stay ahead. doesn't mean we go kill people.

[VaticanIscariot]

@sangohan37 how is it killing people when its their fate to die in the first place.

[sangohan37]

@VaticanIscariot not to be rude but this does not make any sense. killing means ending someones life, whether they are about to die or not if you end their life you have effectively killed them. plus by your rational i could go out and end peoples life and that would not be considered killing because as we all no we are all going to die someday. i will say this again, this is one of the most radical inhumane idea i've ever heard.

after the handicap who's gonna be next , "stupid" people??

[VaticanIscariot]

@warren52nz i argue the same thing.. and people accuse me of eugenics >.>

[warren52nz]

@VaticanIscariot It's a tricky subject and I'm intentionally ignoring the moral issues. I don't think we can (or even should) stop people from having children no matter what their genetic failings might be. I suppose you could argue that as modern medicine fixes the problems in individuals, it doesn't matter but I wonder how well this will work long term. We may end up with a seriously weak gene pool. I know it's a touchy subject so I don't want to push any particular view out there.

[Skorpi00007]

@warren52nz I have to disagree. Thats just the same thing the nazis tried to back up when they killed are the retarded humans. If you interested i show you a video of how other animals treat their ill in society. They take good care of them and even try to heal them

[warren52nz]

@Skorpi00007 As I said it's a tricky subject and I'm not taking a side. I'm just saying that humans have mostly destroyed Natural Selection with modern medicine and morality. I'm not saying that's a bad thing but I wonder if we can do a better job than Evolution has done over the past 4 billion years or so. I'm no Nazi, just pointing out the blatant facts for what it's worth. Not all facts are palatable.

[pureefficient]

@warren52nz If they can reproduce and survive that only means natural selection is at its prime. Clearly an alpha organism would take advantage of such sympathy and reap its benifits. Out in the wild advantage is everything. But on the serious side note you must know that everybody is raised differently. Humans have varied attributes. Being intelectual,strong,agile,creat­ive.  If you were to allow certain things there would be no order. Thats like giving people right to rape and kill

[pureefficient]

@pureefficient And my arguement goes on. Many species rape and kill to assure their genenome passes on. If bieng devious is what you need to be ontop of it then there would be no social order. Some people will never be happy with a single mate others will. I would focous on my goals and improving my self worth and i honestly shouldnt be putting up with worthless skanks. Attraction varies on every human differently because of the qualities we want. Beutiful smart people make same.

[warren52nz]

@pureefficient Yes human intervention complicates Natural Selection. It's hard to say what the outcome will be but I think the process is robust and will ultimately prevail. Those that can survive will pass on those survival traits whether it's genetic or learned. If ruthless wins the day then we're headed for a world without ruth I guess.

To address your other point, a society that allows rape, etc is unstable so some form of natural selection will keep it out as normal behavior too.

[archimspart]

Humans need to be selective, like these mammals, about what kind of offspring they will produce.

[xoMISSxoTAYxo]

booby birds

[totaldollar]

.36 "advertisement resistance to disease" poo

[totaldollar]

.36 hahaha

[cutefappy]

hmmmm i think the male humans will be more attracted to those male birds than the female birds =|........just saying, they kinda have something that that uhmmm might trigger a man's uhmmmm...."antennas"

[southsudanvoice]

that's sucks.. for the red spot

[100flyingfish]

its a strip club

[snakepit000]

Aww.. virgin for life... :[

[thebenchwarmer]

wow.. that's so weird.. looks like jugs.. hahahaha. awesome vid!
