"Evolution is a tinkerer"

Francois Jacob's quote "Evolution is a tinkerer" is a metaphor for the process of evolution. It recommends that evolution is a procedure of trial and error, where organisms are continuously adjusting and changing in order to survive in their environment. This tinkering procedure is driven by natural selection, where the fittest organisms are more likely to make it through and reproduce. Jacob's quote implies that advancement is not a linear procedure, however rather a complex and unforeseeable one. It also recommends that development is not necessarily directed towards a specific objective, however rather is a continuous process of adjustment and modification. This quote highlights the value of adjustment and change in the evolutionary procedure, and emphasizes the significance of natural selection in driving this process.
