PPT-Modification by descent (homologous structures)

When there is a similarity of the formation of a body part or organ due to a common evolutionary origin it is termed a homologous organ Biogeography D ifferent but closely related species in similar biomes across the world have similar features in adapting to that biome indicating that they probably developed from a common ancestral .

Broccoli and Cauliflower evolved from Mustard. print. Homology: A Bouquet of Broccoli One wouldn't normally munch on a rosebud or snap off a dandelion flower for a quick snack. But in fact, in terms of homologies, when you eat broccoli or cauliflower, you are doing just that. Although not scented or suitable for centerpieces, the green tips of broccoli and the white tips of cauliflower are actually flowers. Through many generations of artificial selection, farmers modified the bright yellow blooms of the wild mustard plant into the edible, vegetal plant parts you'll find nestled next to the ranch dip on the hors d'oeuvre tray. .
