Innovation is if anything under-rated and under-funded and under-supported. The homes of hundreds of millions of people and energy itself is threatened by depleting fossil fuels and global warming...and some of the major efforts to stop this have depended on effectively "insane" entrepreneurs like Elon Musk...not a smart system! All the while hundreds of billions of dollars in health care costs for just say unnecessary tests flows to negative value addition maintainers.
Maintainers mostly either conservatively follow & accept or exploit the current system. It's innovators who've driven down the cost of lighting your home to a few hours of income or the ubiquity & cheapness of books & information (perhaps to the detriment of wisdom but that's another story) to stopping war through protest to ending non-man-made famine.
How do you even get to a sharp stick without innovation?
Basically peasants, once kicked off the land end up herded into cities.
Presumably the thinking at the time (beyond "lets make ourselves rich") was that agricultural production is more efficient when undertaken as a large-scale concern rather than by scattered small community holdings.
Or the invention of the various tools to actually make the agriculture viable and progressively more efficient.
Also provides an interesting corollary on the consequences of innovation.
Evolution? That's how agriculture and many of our earliest tools were created. I don't think there were many/any single steps that we would consider innovative.
We may have had a very suboptimal way of doing it for centuries while the process evolved. I'm sure a lot of people here have stories of their pets confusing cause and effect.
