I have to complain a little, though: the title says the observation of shared molecules between molluscs and humans “proves” we’re related. I really don’t like the use of the word “proof”, because it doesn’t — it is compatible with the hypothesis, or it supports the idea, but biologists don’t dabble in proofs.
There’s also an error on my part: I somehow transposed the stomach and liver. I know where these organs are, seriously — I teach part of an A&P course — so I blame my too-fast typing. Now no one is ever going to let me take a scalpel to their abdomen, ever.
