"I will believe in Evolution when a monkey gives birth to a human baby"

I will say it once more, the humans didn't descended from monkeys, we just share a common ancestor with them. It turns that the common ancestor was/looked a lot more like a monkey than a man, and we would have probably called it a "monkey" if we had found it twenty-five million years ago. But even though the humans had evolved from an ancestor that we would call sensibly "monkey", no animal gives birth instantly to a new or different species, or at least a none so different from itself as a man is from a monkey, or even from a Chimpanzeee. It is not of what evolution is. In fact, evolution is not only a gradual process, it < has > to be gradual if it wants to do a exploration work. The huge jumps in one generation-, as would be considered that of a monkey giving birth a man, are almost as far-fetched as the divine creation, and are discarded by the same reason: too unlikely from a statistical viewpoint. It would be nice if all those opposed to evolution are bothered to learn a little of the basic rudiments of what they oppose.

Otra vez, los errores en negrita son los más graves gramáticamente en los otros son estilísticos o no son tan graves.  En general, esto es mucho mejor que tu primera nota, aunque haya bastantes errores — las estructuras son más complicadas.  No sé que quieres decir cuando dices 'exploration work'.
