Mutation it seems is not so random. There seems to be an evidence of well-coordinated effort to make possible the emergence of complex organs. The article here talks about a research report.
It talks about a term called pleiotropy defined as, "The phenomenon wherein mutation in a single gene can have effects on multiple traits is known as pleiotropy."
A conclusion of sorts from the author believes pleitropy is not random - it is well-coordinated. "Similarly, it appears that tuning up a complex trait in a living organism is well coordinated and the effects of pleiotropy are more focused than we thought."
If mutations are not so random - but coordinated, who and how they get coordinated.
I really need to understand - is there a possibility of uncaused emergence?
