Or the last chance we are as spices (Again) The world needs to be as one.The fact that the vast majority of the species that have existed on Earth have become extinct, has led to the suggestion that all species have a finite lifespan and thus human extinction would be inevitable. Dave Raup and Jack Sepkoski found for example a twenty-six-million-year periodicity in elevated extinction rates, caused by factors unknown (See David M. Raup. "Extinction: Bad Genes or Bad Luck" (1992, Norton). Based upon evidence of past extinction rates Raup and others have suggested that the average longevity of an invertebrate species is between 4-6 million years, while that of vertebrates seems to be 2-4 million years. The shorter period of survival for mammals lies in their position further up the food chain than many invertebrates, and therefore an increased liability to suffer the effects of environmental change. A counter-argument to this is that humans are unique in their adaptive and technological capabilities, so it is not possible to draw reliable inferences about the probability of human extinction based on the past extinctions of other species. Certainly, the evidence collected by Raup and others suggested that generalist, geographically dispersed species, like humans, generally have a lower rate of extinction than those species that require a particular habitat. In addition, the human species is probably the only species with a conscious prior knowledge of their own demise, and therefore would be likely to take steps to avoid it.

Humans are very similar to other primates in their propensity towards intra-species violence; Jared Diamond's The Third Chimpanzee (ISBN 0-09-980180-9) estimates that 64% of hunter-gather societies engage in warfare every two years.

Stern! Where are you and foxy, the old or young thing?.lol.

Yes its called evolution

As for “human extinction would be inevitable.”

I suppose i should try to decide whether to do the irresponsible thing

Spend what resources I can muster and have a party

Or the responsible thing

Spend whatever sources I can muster on an insurance policy

Speaking personally, I think I will stay straddling the fence, do neither and hope that I manage to shuffle off this mortal coil before the extinction happens

as for old or young... try grey roofing tiles with a new fire burning in the grate

"Speaking personally, I think I will stay straddling the fence, do neither and hope that I manage to shuffle off this mortal coil before the extinction happens"

Yes Agreed. but I tend to be more optimistic since my roof tiles are not quite in the spectrum of that particular colour scheme. smile.

But the above does point out that mankind has the power to holt, to stop the extinction, by governments promoting campaigns with the reality based facts which can alter the minds of the young peoples of this planet in A hope they see and breed less.

And knowing humans as I do and yourself, they will just roll along until the sh@t hits the fan. But before that happens, you and I will be long gone and your children,s children,s will be quite old indeed.

If something can be done to slow the processes, to give humans a century or two longer, I think this is worth doing.

Stern.
Mammals of all shapes and sizes is my PHD is in the study in this particular instance of the current time line which mammals present themselves in co-ordnance of our species. The true fact is, is that our species can not stand each other and we only come together when breeding time suits our values in correlation of the species particulars in the category of mammals as a whole. So what this means you humans have forgotten their place in time, and the extinction which is relevant in all mammal species does and will dictate the terms and conditions of not only our species but all mammals in a whole as well as given the time line of our existences does not value us as anything important to the time line which we now present ourselves in. Dinosaurs had their time and produced nothing worth while and I guess the gods also agreed with this on this particular train of thought. Yes Stern, it is basically evolution and the religious value was invented to tame the mammal thoughts which in turn created our societies and our histories and all that we have investigated throughout our short times of being here, which you all can see we are having a catastrophic affect with us being mammals in the way we do things.

Mammals are a new invention which I must say are a negative with there larger brains and the fundamental facts are, and I will say this to all human mammals,

Look deeper within yourselves, the face you look at is the three faces have I.

And guess who you are.

All the best.

Just some food for thought.
