_at_ Mafer: I am not sure with your question, why do you choose the question word "will"? :roll: One more thing, what do you mean by "alternation of generation"? IS it the same thing happens in moss and fern's "metagenesis"... Well I don't think so :?

@Amrik: Why do you put "women" in brackets? Blastula and gastrula are common in human, even all animals development :?

To answer the original questions:

Humans do not go through alternation of generations. Very few groups of animals do.

We do go through blastula & gastrula, but not in the classic "ball" shape (most vertebrate blastulas are really a hollow disc, sitting on a yolk).
