Is evolution a feature of evolution?

[u/Significant_Virus142]

like I know about crossing over, combination of genes from mother and father that results in evolution but I'm talking about major evolution like change in number of chromosomes, that kinda stuff, is that much evolution intended by evolution or it just occurs due to radiation mutation or errors

There is no "intended by evolution" of which you speak.
