What you described would be called, I think, convergent evolution by the darwinists. What is the probability of such convergence? I would expect that it is a very large number against.
I see design all around us. I see genetically designed cotton, wheat and chimeras that fulfill the definition of evolution which can be defined as "any change in the frequency of alleles within a gene pool from one generation to the next." Helena Curtis and N. Sue Barnes, Biology, 5th ed. 1989. So while a preponderance of scientists dismiss design out of hand, I don't since I can observe it with my own two getting old eyes.
Of course I'm not a scientist, I'm a blue collar guy who managed to collect a BS in engineering when I got out of the Army. So, you'll have to take my points with a grain of salt.
The fact that you can stand there and know your existence, while others keep reinventing or changing theirs - it's quite refreshing!
