Premise 1) Sundews are found on several continents. Premise 2) There are critters that occupy the same niche in different locations, with similar appendages but are not related. Premise 3) There are critters that are related but don't look similar and don't occupy the same niche (horseshoe crabs vs. spiders). Question: Are the sundews from the various continents related to one another or are they just occupying the same ecological niche and look similar? The same could be asked of pitcher plants and butterworts.
