Coelacanths have had well over 400 million years to 'advance', but I don't see them reaching for the stars just yet.

You need to read all the posts.
We evolved as did Coelacanths...simple as that.

And of course some species evolve, some become extinct due to many diverse reasons.
Some may never advance beyond single cell stuff and are happy and not troubled in their own little world.
In the end though, its time that is the certain and common factor for evolution.

[Talicoabilk]

but evolution doesn't mean eventual intelligence.

[mirex]

no

[mikelangr]

Every species on earth has spent exactly the same amount of time evolving

Not so sure I would agree with that...

I never said that.

Not all the elements etc created in the belly of stars reach relative intelligence either.

It's really quite simple... time, while being a factor in the level of technological advancement of a civilization is not, in itself, a measure of the level of technological advancement of a civilization.

Agreed.

So does that mean, that even though they may have a million years on us, as previously stated, this still doesn't mean that they will be smart enough or more technologically advanced than us?

That is one possibility

[paydayuscf]

yes, there is that possibility.

[HcMkOKiz]

yes, there is that possibility.

Ok.... So given that the OP wants to search for evidence of alien technology, what's that got to do with that technology being "green"?

Are we going to find signs of life before we find signs of technological advancement? So in essence, time really doesn't have anything to do with it, other than as a measure of distance?

[mdUzAMbG]

Are we going to find signs of life before we find signs of technological advancement? that is the most likely scenario."likely" being better than zero.

[Jueqelyl]

So given that the OP wants to search for evidence of alien technology, what's that got to do with that technology being "green"? maybe less easy to detect a "green" civilisation than a wasteful one. more extraneous emissions of emr, gases etc.

Intelligence does not rely on time or environmental change and is certainly not the end result of any evolutionary path. In the case of Homo and its ancestors we would not have evolved intellectually had we not the means to adapt and in our case having hands to manufacture a range of sophisticated tools.

Such attributes placed us in a position to advance and coupled with environmental change made us think of different ways to survive. This in turn would stimulate the brain to be more inventive, and so develop to become our greatest asset (assisted by our dexterity), which can be clearly seen by the gradual increase in brain size.

Other intelligent beings, although they have been around for as long, or longer than our line of evolution have not developed past an eliminatory stage simply because they do not have the physical ability to manipulate items to the same extent that a pair of hands are able. Because of this, their mental processes are restricted, as they are limited to what their physical bodies have evolved to perform.

Just another possible scenario as already explained.

Quite possible, but time is always a factor.

Many variables with the possible stages of evolution, but time remains an important factor for the reasons already given.

Hands are not the sort of thing you can make happen in order to improve your brain capacity, as are flippers, hoofs and paws. These developments go back a very long way to suit niches available at the time. They are not capable of radical physical change.

[mr.calisto]

So, forgive me, but can someone spell out the purpose/question of the OP? Very little words please?

[RichardHaads]

I'm not at all arguing any of those points....but it still entails time.

A new scenario with regards to ETI.
