Q9. Here is a hypothetical evolutionary tree showing domestic and wild pigeon populations. If this were the real tree (it's not), how many times would you infer that pigeons have been domesticated within the populations measured here? Wild Pigeon 31 Domestic Pigeon 24 Domestic Pigeon 15 Wild Pigeon 12 Wild Pigeon 10

Communities and Ecosystems

Ecology contains two words: Eikos means dwelling, and logy means to study, so the combined meaning is studying habitat or living.
