Okay, let's discuss one in particular. Do you have a favorite?
Thanks.
No fav, just reading what was posted.
Not a bad article. First one concerning the e.coli at extreme temp's and the survivability/fitness. First glance, the generations are comical, 2000-10000. Hard to compare to humans.
If wiki is correct and 200k years has been since man like creatures, and a "generation" of 40 years, that's only 5000 generations.
If its only 50k years for man, and generation is 40 years, that's still only 1250 generations.
My ultimate point is: bacteria survive by recombining plasmids/mutating etc., higher mammals protect this with greater care.
We just don't have time for us "higher" mammals to really "mutate" into a finer organism.
So the question is what has changed with us since the 200k first man like being. Did it take 150k years to go from an anatomic modern human to a modern behavior human.
In that 3750 generation, frontal lobes connected due to mutations? Is that enough time? (The last 6000 years [150 generations] we haven't really changed much [not accounting for the exponential advancement of knowledge in the last 100 years]).
At the end of the article, they are still looking for the molecular basis of adaption.
That would be the holy grail.
In that, we can test if the DNA actually has programming for changes due to stress (which would be favorable to ID) , or its just damaged/changed and this is filtered by fitness in the long run.
Just my take after a brief reading.
