Darwin's Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers -- all related.

Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification".

It is composed of five basic parts: a catch (to hold the bait), a powerful spring, a thin rod called "the hammer," a holding bar to secure the hammer in place, and a platform to mount the trap. [4] Darwin's Theory of Evolution - A Theory In Crisis Darwin's Theory of Evolution is a theory in crisis in light of the tremendous advances we've made in molecular biology, biochemistry and genetics over the past fifty years.If any one of these parts is missing, the mechanism will not work. We now know that there are in fact tens of thousands of irreducibly complex systems on the cellular level.When students' curiosities are peaked, they will learn on their own, the teacher just scaffolds. Students need to know enough to be curious but not more.Use students' prior knowledge to drive differentiation.Suppose a member of a species developed a functional advantage (it grew wings and learned to fly).

Its offspring would inherit that advantage and pass it on to their offspring.

That is, complex creatures evolve from more simplistic ancestors naturally over time.

In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival -- a process known as "natural selection." These beneficial mutations are passed on to the next generation.

Darwin wrote, "…Natural selection acts only by taking advantage of slight successive variations; she can never take a great and sudden leap, but must advance by short and sure, though slow steps." [1] Thus, Darwin conceded that, "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down." [2] Such a complex organ would be known as an "irreducibly complex system".

An irreducibly complex system is one composed of multiple parts, all of which are necessary for the system to function.
