Really ? And who told you that if I may ask ?
The most likely explanation still talks about hydro-thermal
vents and no solution is as yet considered too be likely
enough to be called correct.

Well, he didn't say how many trillions...

Really ? Please, ellaborate. (Notice: he said conditions NOT
make-up.)

Indeed.

Also, lighten up dude !

Peace and long life.

BTW, I recently saw a chapter of Evolution (a remarkable
series, btw) about mating and a scientist proposed a
possibilty that says our brains evolved as a means of
sexual prowess, same as a peacock's tail. Fascinating !
(I wonder if he'll personally succeed in supporting this
idea with sufficient evidence before some feminist fanatic
shoots him... )

Drag. Simply put the 100% meaning of life is to pass on your genes. More specifically, the meaning of life is to produce offspring which are able to produce their own offspring.

Absolutely positively without any doubt whatsover, every single species and every single factor, adaptation, ability, quality etc... evolved for the sole purpose of breeding.

You have eyes to see your mates, and do avoide anything which will inhibit your breeding

You have ears to hear your mates and avoid anything which will inhibit breeding.

Legs to find mates and escape anti-mating factos

SO of course the brain serves one purpose - to be more successfull at finding mates which will be able to produce offspring.

It's nothing new in biology.

You are correct in general. However, the specifics are still
quite debatable: Was it the advantage of the people with
the larger brains who used tools and improved them that was
the primary cause for the development of our brain (as was
thought until now) or was it the ability to attract females and control more of them directly by being smarter as well as
get rid of competition by displaying greater wit ?

Live long and prosper.

Firstly, no I am correct in whole. I am trained in biology to the highest degree possible. And specifically, beyond that, trained in neuroscience.

You exactly answered yourself. HomoSapiens who were able to use tools could perhaps access food quicker, and not be the ones with no food in the end. They could use tools to fight off predators better and thus live longer and breed more.

Abslolutely every single factor and motivation is to pass on your genes. It is not ones individual choice - it is a preditermined requirement of being ALIVE.

But maybe that was just the side-effect. Purhaps the primary
reason was the fact that a girl would go with the dude
who understands her better and can ammuse her and directly,
because of that, treats her better and attracts her more.

Live long and prosper.

Error.

"go with the dude".

Pre- Homo Sapiens do not pair of life. There is no relationship between them.

Secondly, she would not "go with" anyone. A male sees a female he wishes to mate with and does it - the female has NO choice in the matter.

?! Even insects have, sometimes rather ellaborate, mating rituals.

We'd wish...

Wouldn't that solve a lot of problems.

could life be created outside of a planet? like in a nebula or protostar cloud for instance?

there are such speculations...e.g., life forming in the cores of comets (heated via radioactive decay, the cores would provide shelter from space, a source of liquid water, a source of organic compounds in close contact, etc.)

obviously, there's no evidence that it has happened.

I think it was obvious that he was just implying a large, not exact, number.

4. You say you can't believe not another planet has remotely our conditions. In fact scientists have identified MANY planets that have our same make-up.

No terrestrial planets outside our solar system have been found yet.

Science can pass no such value judgement. That may be a generalized observation of gene function, but "meaning" is something else.

Absolutely positively without any doubt whatsover, every single species and every single factor, adaptation, ability, quality etc... evolved for the sole purpose of breeding.

No scientist possesses such certainty. Also, evolution does not happen with intent (or "purpose" as you put it). Gene pool changes can occur for reasons other than better breeding. Differential success at breeding can be linked to each change perhaps.

You have eyes to see your mates...

You're stretching the point way too far.

Such a state is not possible. Even the top biologists in the world have more they can learn from others about certain aspects of biology (at some level of expertise, one begins to specialize and become less familiar with other aspects).

You exactly answered yourself. HomoSapiens who were able to use tools

Essentially, all Homo sapiens were tool-users.

Abslolutely every single factor and motivation is to pass on your genes. It is not ones individual choice - it is a preditermined requirement of being ALIVE.

Passing on genes is certainly a big factor...but not absolute.
What do you say of those people who choose not to breed?

Yeah, but intellegent life ?! That's just out there...

There is no intelligent life out there.
