As a matter of fact, with the advent of genetics, we’ve found may species that are alive today that were determined to be the same species despite looking quite different.

And the reverse: populations that are determined b genetic analyses to be different species in spite of appearing morphologically to be identical, or at least very very similar.

Yes, that is absolutely possible and also very, very likely. As a matter of fact, with the advent of genetics, we’ve found may species that are alive today that were determined to be the same species despite looking quite different.

How easy/difficult is it to identify adults and larvae in the fossil record? If for example, a fossil impression of a caterpillar and a butterfly of the same species were found side by side in the same rock strata, how would one go about determining that the two are the same species?

Is it possible that some specimens (from, say, a Cambrian deposit, for example) currently classified as two separate species are actually a larvae and adult form of the same species?

2. “publiconormative old guard GOB networkians” – is that a sciency term? 🙂

I know someone who is in 3rd year PhD in computer science networks. Maybe I can convince him to title a paper with that.

3. “publiconormative” – my spell checker hesitated trying to decipher that one.
