The small hopping insect Issus coleoptratus uses toothed gears (magnified above with an electron microscope) to precisely synchronize the kicks of its hind legs as it jumps forward.

You have no clue what "Chaos" actually is in the sciences.
Chaos theory is a branch of mathematics which deals with phenomenon which aren't able to be predicted due to their original conditions not being known or easily measurable, such as how theoretically, a butterfly flapping its wings in China could cause a hurricane on the Midwest.
"Chaos" has nothing to do with evolution, or "random" (which doesn't even mean "random" in the sense of what people imagine a slot machine to be; and in reality, slot machines are not "random" to begin with, they have the illusion of being random but are configured to work in the exact way they do).
The entire notion of "randomness" or "random chance" is just superstitious popular slogans and folk wisdom, as well as just complete bullshit, having more in common with ancient Greek mythology, such as everything emerging from a primordial void known as "Chaos".
That's the entire opposite of what Newton's physics are based on to begin with; in ancient times, people such as ancient Greeks believed that the laws of nature were "random, chaotic, and unpredictable", dictated by the whims of pagan Gods, whereas Newton's physics revolutionized things, by showing that phenomenon such as gravity followed orderly, predictable mathematical laws, rather than "randomness".
