Why this continues to happen in flora and fauna is a mystery. Its one of those 'why' questions, that may very well have a definitive 'how' answer.
Sorry what is a mystery? I can't see a mystery here.
That protein sequences and chemical bounds through chemical functions allows for division, rebounding growing in number, and why & how that translated into organic life.
I consider that mysterious. I like things being demystified though.
Human beings are unique in our application of our mind.
While I'm at loss why we are discussing this now, my opinion is that it is not clear in how far the difference in between humans and other species is really qualitative or categorical, and not just quantitative. As for consciousness specifically, I am of the opinion that at the very least all mammals have conscious experience (i.e. aware experience - not necessarily self-awareness, though), seeing as all mammals are using essentially the same hardware brain-wise, qualitatively speaking.
Animal cognitive science is still in its infancy, only recently has there been a decent amount of work done. It seems like animals have a variety cognitive attributes, though select few of them. Like some breeds of ants can count, and chimpanzee can do basic math and remember a good range of numbers. It seems like animals have some deceptively good input devices for their instincts.
Though neither of them can do game theory or industrialized yet.
The main issue here is the continuum of instincts and ability of fore thought. There hard extreme boundaries and a fairly fuzzy middle.
No, the main issue here is that you, like so many others, seem to think that following one particular evolutionary trail to a successful end somehow elevates us above everything else that lives on this planet. It's this inflated sense of self worth that leads to incredibly mind-bogglingly stupid concepts like Humans being unnatural.
I DO?! HOLY SHIT! PRAY TELL, WHAT ELSE DO I THINK AND BELIEVE? PLEASE TELL ME, WHAT I BELIEVE! WHAT ARE ARE MY OTHER STANCES ON OTHER TOPICS?! BECAUSE THIS IS SHOCKING, I DIDN'T KNOW WE HAD A TELE-PATHETIC PERSON IN THIS THREAD!
Seriously, what? When did I say human were unnatural? I'm right here, participating in this thread you can ask me if I thought that or ask for clarity.
And I've stated we're smarter then most other animals on the planet and unique in its application (and again to our planet), unless I've missed something and there is a secret super advance city of apes in africa with cloaking technology and flying benches. Oh, and they also have direct energy weapons too. Or bottle nose dolphins secretly live in atlantis where they've industrialized and surpassed the nuclear age. What we've seen so far, is the dolphin equivalent of amish dolphin who live in comparatively paleolithic hunter gather societies on purpose.
Hell, if you want to talk to me, one of my zanier unfounded speculation on marine mammal culture is that they have a religion of some sort. That neigher here no there.
No human are animals like any other, our predomiant evolutionary advantage has afforded us luxury & understanding unseen in nature though and continuation to shape our future with generational foresight.
Since human are animals we are susceptible to natural instincts and pressure.
I have a friend, by the name of JohhnytheSquee who believes being sapient is an unnatural development. He not terribly knowledge on evolution, or human evolution, or science in general, and believes that being sapient is unnatural because of bottle nose dolphins since their brian is of similar size of our.
Although his source fails to take into account a good portion of a bottle nose dolphin brain are a fatty tissue to prevent the brain from being to cold, so its not as large as it looks. He also believes that 9/11 was caused by Bush, when he thinks that all government are boobs in general.
I think his notion is silly since we clearly see the foundation in other races for our level of intelligence and sapient creature exist in other races, such as the dolphin he pointed out.
