That is not evolution
> In fact, bacteria are the most adaptable life form, able to make big changes that will remian that way. For eg., they can change from being able to survive in acid conditions, and then change, adapt, to thrive in alkaline conditions within just a few days.
What you are describing occurs without any change in genetic information. Bacteria are able to adapt, it is thought, by switching "on" and "off" certain genes under different circumstances. The genetic information stays the same. No evolution occurs. This can occur within the lifetime of a single organism and is a biological process, not an evolutionary one.
> Consider that the steroids that make them stronger cause some chages to the chromosomes and DNA - the offspring will have that change too.
Taking steroids doesn't make your children stronger!! This is another example of Lamarckian evolution which has been totally discredited even by evolutionists. The only way you can change your genetic information is negatively - e.g. by big radiation doses.
> There might be times on earth when those conditions are more pronounced, like in a time of magnetic shift that the earth sees every 200,000 years or so, a shift which we are over-due for now.
The magnetic field of the earth is constantly shifting, but is far too weak to cause genetic mutations.
> And it is human nature to kill the freaks off, in our animal past anyhow, and in Jr High schools!
What kind of high school did you go to??? ;-)
It seems to me that evolution is such an all pervasive metaphor in our society that people take it to be true without questioning it, without even understanding it.
