The problem with definition #2 is that in biological evolution the ontogeny of an individual is not considered biological evolution as individual organism do not evolve. It is the changes that occur within a population that are inheritable via the genetic material wich are considered biological evolution. That important destinction was not made clear in definition #2.
That is also why the correct modern definition of evolutionary theory is stated as "the change in allele frequency within a population over time."

why don't you use the definition given in the article you cite instead of something worded differently?.....
"Evolution is a process that results in heritable changes in a population spread over many generations. "
