@Ionus,
Quote: For example, not wasting resources, not overpopulating without a mass kill-off, a method to kill off the old and the sick as a survival of the fittest mechanism to prevent wasted resources, etc.
. The above concepts (the word I believe you want to use is "tenets" ) wre the bases by which Darwin had compiled his theory. He was a student of MAlthus and by considering various means of environmental "Pressures", he was sure that , scarce resources or overpopulation,were the :"mechanisms" of evolution. SO if we consciously try to avoid these "rules" we can avoid extinction events that are self imposed.(I dont think we can becuase we, as a species, have created too much anthropocentrism and xenophobia in our societies. (We dont help out our fellow humans and most governments in need of help wont accept it and will allow their people to starve)
Personally evidence clearly shows that we danced on the edge of extinction many times . The most recent and therefore the most famous, and one that is recorded in our genes is an extinction sized event that occured about 70000 years ago with the eruption of Mt Toba. Toba was a "supervolcano" and the eruption caused several years of resource pressures from mini "nuclear winters". The resultant die off of the human race was supposedly quite severe. We were whittled away to a few thousand to not more than 10000 individuals PLANET WIDE. If the Snake River caldera were to blow (It has the shape of our entire Yellowstone National PArk) like it did 700000 years ago, the US would no longer exist as a nation and half the people on the planet would be killed either initially or as the resu;t of several years of NO SUMMERS. (There is a marked tilting of this caldera since the 1930's when the seismic network was installed)
Quote: Extinct species have had one or more tenements that they could not fulfill. If we are to control our environment, shouldn't we allow in these tenements or risk evolving into an unfit species and becoming extinct ?
We try to control as much of the environment as we can. (We are a pretty fucked up species so we are always being faced with starvation in several spots on the earth .However, most of the environmental pressures that may cause us to go extinct as a species are exogenous, in that they are beyond our controls. (eg Bolides "smack downs", supervolcanoes(there are at least 5 of these all over the planet), extreme climate change due to axial wobbles or our sun going supernova or (as we are experiencing now--a sunspot minimum); As our magnetic dipole begins to erode as the poles flip, will a portion or more of our atmosphere be whittled away so that only sherpas (now considered a sort of sub species) will survive and thrive?). Theres gotta be a bazillion ways that we can go extinct , but the biggest rule we have broken in successful "evolution " is that we are only ONE species. SIngle species have always been the ones to have gone extinct over genera with multiple pecies.
I dont think we can knowingly avoid extinction. Theres too many exogenous things out there with our name on em. According to Ellis and Lleaky we have already gotten to the edge of sustainability (That was from some half baked theories of the 90's).
There are several international "Think tanks" that are studying these phenoms but , like any think tank, I know of nobody coming up with any answers.
May we live in interesting times.
