@eindecker: OOH, a fellow Pop Sci subscriber,
Yeah, I love Pop Sci.. My sis got me my recent subscription as a gift, and as soon as I got that first issue, I forgot how much I missed it.
how advanced or primitive a species may be is irrelevant considering the context that even though we may consider ants very primitive compared to our technology such as automobiles and electronics even though ants and most insects are more efficient and successful than humans.
ultimately much of what the human race considers to be advanced or vital in defining the achievements of life forms are completely irrelevant to survival or beneficial to the species ability to become more successful. if yo consider the fact of it, all most every part of your daily job is dedicated to the production of luxuries that are not necessary to survival as a species, unless you work in agriculture or production of building materials and so on.
Well stated.
I often think about how trivial our work and lives are at times, especially those who's only aspirations are being more popular and wealthy than the next.
There is no doubt that the amazing combination of natural selection and random chance can and has produced things far beyond what we could ever imagine.
This is why I have trouble ever enjoying movies with aliens. They're always so unrealistically similar to life on Earth that I can't bear it. Bipeds, with heads, eyes, ears, mouths, arms, legs, skeletons, muscles, feet, hands, veins, scales, teeth... I could go on forever.
While I'm sure there there are anologous parts on many alien organisms, and maybe even exact structural copies (the eye has evolved multiple times, independently just here on earth), I suspect that there are complex organisms that have almost none of these attributes, and I'm tired of people designing boring aliens for fiction.
One interesting concept that deserves lots of exploration is organisms where the line between colonies of unicellular, and multicellular organisms blurs. What is a human but a colony of clones created by a self-replicating cell, that have differentiated in response to environmental conditions? There are other organisms that we consider unicellular, but have differentiated individuals that serve different roles within a colony.
One thing that has always fascinated me are colonies of microorganisms working together to perform the function of one larger, more complex organism, such as Siphonophores.
