Default Homosapien! Pandora's Box or Masterpiece?

Is homosapien an evolutionary Pandora’s box? Or nature’s finest masterpiece?

Life mutates as it progresses through time via natural selection. Niches are filled, predators become better hunters, and prey becomes better at avoiding the predator.
Throughout the history of the earth, there has been no greater impact on the planet than that of homosapien.
If we go back to the time of the dinosaurs, we know that they lived on the planet for millions of years, yet they themselves did not affect the ecology of the planet in their entire existence as we have in less than two thousand years.
We are responsible for diminishing rain forests and other habitats, of pushing species to extinction in their hundreds, and, possibly, of having an impact on global warming.

The progress of homosapien seems to start with the introduction of grass and the reduction of forests that at one timed covered the planet around twenty million years ago.
The ape-like ancestor of humans then had to cross these large plains of open space to reach other trees in order to feed and expand. IIRC, the general consensus is that walking upright became a better way to cross these plains, if not for speed then for a better view of any predator approaching, and by this our ancestors were allowed to use hands for manipulation rather than for walking on.
This then required a larger brain for increased dexterity and control, which over the following millions of years ultimately led to the humans of today.

Yet now we are responsible for damage to the planet from many quarters. Whether it is technology, agriculture, industry, or humans own weapons of self-destruction, there are no doubts they we have played a huge part in the demise of many species and are pushing earth to breaking point.

The political or moral point of this is not the aim of this thread, but to wonder if evolution got it wrong.
Would it allow the creation of such a species to decimate the planet as we have done? Was it taken out of evolution’s hands the moment we began to walk upright and forced evolution upon ourselves? Are we its greatest creation that has yet to fulfill its true potential? Or is it just pure inevitability that us, or a species like us, would eventually be where we are today?

Inevitability would seem to be the right answer, but there has been no other species on this planet like us. We are unique to this world. And even dinosaurs in one form or another never even approached the complexities of a human being, and yet they had hundreds of millions of years to work at it.
Yes, we could say that the meteorite impact and the huge volcanic activity of the time pushed mammals ahead, but the evolutionary jump from instinct to reasoning must be the crux of the matter.

Of all the species that have come before us, we are the only ones that can now control our existence rather than existence control us. Be it disease, famine, predators, or earth’s own upheavals and climate changes we have overcome what it has thrown at us – but have we pushed beyond that which we were equipped for?
Has evolution met its match in homosapien? Or is it patting itself on the back?

animals arose and went extinct before we were here, and they will continue to arise and go extinct long after we are gone.
our effect on the earth is still a matter of debate- regardless of what certain wanna be ecological warrior former politicians and celebrities might say about it.
in the overall scheme of things, we are nothing. if we get out of hand, nature's immune system will find a way to eliminate us, and life on earth will go on until the sun starts to boil the atmosphere and oceans away.
so if you want to go on living your life thinking that you are a part of a species that is doing more harm than good, then have at it. but that's a pretty negative way of looking at things, don't you think?

Evolutions is like a rain cloud, that has no opinion on whether its raindrops go towards growing crops, or whether they go towards killing people in floods.

Homo Sapiens is a successful species, in as much as the species matters evolution-wise. As far as I know, we are have the highest population for our weight class, which means lots of individuals have been reproducing. And therefore, we are a success. We aren't a plague a 'virus' to quote Agent Smith, we are just good at this whole 'be fruitful and multiply' thing. However, neither are we the Big Dude in the
Skies gift to the universe. We are just. . .us. Manipulative (tool using) Intelligence is but one path to success, and as is obviously not a common one. Many species have come and gone, most likely we will too. And I don't mean in some billion of years from now 'Heat Death' type death, don't flatter yourself, it could be in a few million years. Who knows?
We are like the man whose goal was to be immortal. He was asked how that was going.
His response?

"So far, so good."

How do you define what's the masterpiece of evolution? Sounds pretty hard to me.
The crocodile, who has lived unchanged and unchallenged since before the dinosaurs?
Or bacteria, who will still be there after a nuclear war, always changng and adapting?
Or human, who have found a way of asking that question?

Or something entirely different...
Think of a race that has evolved beyond the need for physical bodies. Or immortal things of raw energy... or things that could survive a big bang/big crunch. Intelligences vastly beyond our own. Or things so adaptible they wipe out everything else simply because there's no need for any other lifeform any more...

A more objective assertion would be that we are responsible for changing the planet. Whether it is damage is in the "mind" of the beholder. Each species alters the environment usually in a way that over sufficiently long periods of time will tend to work to the demise of the species. We are capable of monitoring the effects we are generating, guessing at corrective action, and monitoring whether that is working---much moreso than other species. We are neither a mistake nor a masterpiece and evolution, exclusive of our skill, cares not a whit. Evolution under our influence will tend to perpetuate us over an ever increasing volume of the universe in a widening variety of conditions. We have found evolution's rudder, but we have a lot to learn about operating it.

You know, the origin of the word 'Masterpiece', correct me if I am wrong, comes from work that a journeyman in some guild would produce to prove his worthiness of joining the Masters of the guild.
If this is correct, the best is yet to come.

Actually crocs have evolved quite a lot, they just haven't had a need to modify the basic bodyshape, which is why they look the same.

And the croc heart is more advanced than ours, with its possibility of bypassing the lungs when submerged, so for masterpiece it's not actually a bad example.

Cool. You learn something new every day.
I'd love to read more about that. How did they tell which parts of the crocs evolved? Wouldn't all soft part evidence be destroyed in the fossilization process? Got a link?

As mentioned before, we are not necessary the greatest and best that evolution can come up with. It becomes very subjective when you start talking about a "masterpiece", some might say bacteria and importantly viruses are a "masterpiece". I watched a program on TV about virus spores that are thought to be swept up to "space" and land on other continents and regenerate (come alive). Other virus spores lay dormant for hundred if not thousand of year. To me that is a masterpiece.

The other part of your question dealt with the fact that humans are changing earth in a way that no other organism has done before, this is not true, we owe our existence to algae/cyanobacteria/blue-green algae these guys converted carbon-dioxide to oxygen through photosynthesis (like plants). After hundreds of million of years these guys found themselves in a major crisis......too much oxygen.

Quote:
The large amounts of oxygen in the atmosphere are considered to have been first created by the activities of ancient cyanobacteria.

The next link is about the Oxygen crisis (imagine that)
http://en.wikipedia.org/wiki/Oxygen_Catastrophe
Quote:
The Oxygen Catastrophe was a massive environmental change believed to have happened during the Siderian period at the beginning of the Paleoproterozoic era of the Precambrian, about 2.4 billion years ago. It is also called the Oxygen Crisis, Oxygen Revolution, or The Great Oxidation......

However, we haven't been successful for very long, yet. It may be that our ability to manipulate our environment will soon exceed our ability to avoid irrational or unexpected catastrophies of our own making and thus put a quick end to our evolutionary experiment in increased intelligence. It could happen in an evolutionary eyeblink, a few tens or hundreds or thousands of years - in fact, if we last a million years it would be a huge success - if we can survive that long, we can probably survive much longer. The jury is still out on this, and we don't know when they will return to render their verdict.

When humanity goes extinct, I would say that is when the test ends. Like Q said, "You just don't get it, do you, Jean-Luc? The trial never ends."

From what Ive heard latley about the progression of man, it seems we just arent as perfect as we think.

We always get diseases and have body problems.
Our claws are a bit crap.
Our teeth arent even sharp
We dont have any fur.
We cant fly unless we have enough money to buy tickets
Our babies couldnt survive a day without us.
Loads of us live on welfare.
Were always predicting doom and gloom for our species

I could go on!

Well, there you have a point. The lesson I draw from it is that any kind of superiority is just an illusion. As we progress in the ladder of evolution, we run into new problems to solve. Sometimes, our own successes seem to generate new obstacles. It's a bit like getting to a higher level in a video game. You have more points, but the game also becomes harder to play.
