I would not use "flawed" but they are "incomplete" at extreme conditions and special circumstances. It turns out they are a subset of more complex equations. For everyday use, these complexity get reduced to something like .000000000000000001 so they do not matter.

I'm trying to remember an example to demonstrate but I am drawing a blank.

Car A is going 100KPH and Car B is going 50KPH faster than Car A. Car C is going the same speed as Car B..... how fast is Car C going?


In classical physics, the answer is obviously 150KPH:
VA + VB = VC


The relativistic equation is:
(VA + VB) / (1 + (VAVB)/c^2 )= VC
where c = speed of light.

(100 + 50) / (1 + (5000)/(1.16 × 10^18)) = 150.00KPH:

Evolution is not a directed force - it does not seek to produce more and more complicated organisms. Natural selection generally keeps things that are necessary and sufficient, and bacteria are living just fine in this world.

Also, bacteria are an entirely different domain of life. Bacteria have gone through evolution, just like the domain that humans reside in. Just as humans and monkeys and fish have evolved, so have bacteria.

This topic always frustrates me to no end. Some people just simply refuse to accept that evolution is real.
Actually, laws would be the highest position. Furthermore, I never doubted the existence of evolution. If you reread the part that you quoted from me, I simply state that the purpose of this experiment is to demonstrate evolvability, that some organisms may exhibit a tendency to evolve more often than others.

I never meant to sound like I was accusing you of being a doubter.

My sincere apologies for misinterpreting the intentions of your post then.
