No, youre not entirely right there.
It's not so much as threats to our susrivial that cause evolution, threats to our survival cause adaptation, not evolution. Adaptation is us using
our minds to save ourselves...
Evolution is the process of slight mutations in our DNA structure. Essentially a long series of gradual DNA screwups.
As these screwups occur, those mutations in our DNA that prove to be useful to our advancement are the ones that carry on. Typically this is because
those with the new unexpected feature can survive easier, hence can focus more on breeding than the others without that mutation in their DNA.
These mutations occur all the time. Most of them are NOT useful, and typically would be eliminated through natural selection. Say you were born
genetically blind... woops, cant use that, you die.
However, in todays world, we seem to be obsessed with giving everyone a future... this contradicts natural selection, as those with faulty genetics
will live, when they should have been weeded out.
A fraction of our species will inevitably experience improvements... but the majority of our race will 'evolve' in a negative way, simply because we
kept them around.
We aren't evolving in a positive direction any more, more like we will see a huge variety of modifications the further we go. Very few of these will
be useful changes to our anatomy, most of them will be a hinderance to us, rather than a useful evolution.
Now, lets take into this, the knowlege that we have gained on how to modify DNA ourselves. Seeing as we will soon have absolute control over the DNA
structure of our future offspring, very soon natural evolution will be a moot topic.
Essentially, why should we wait dozens of generations for a major evolutionary pattern, when we can immediately implement whatever changes we want
onto the next generation.
This very concept of giving our future children absolute genetic perfection will be the end of our own evolutionary path.
