Meanings of ancestral character in английском

Lower case letters (a-d) indicate ancestral character states, and upper case letters (A-D) indicate derived character states.

We then related these to changes that correlated with shifts in lambdamax by reconstructing ancestral character states using a maximum-likelihood approach.

But others could be linked in a series, with the parent as prototype, either by loss of ancestral characters or by simple quantitative alteration.

We can understand these facts, on the well-known principle of reversion to ancestral characters, if all the domestic breeds are descended from the rock-pigeon.
