PPT-Homologous, Analogous, and Vestigial structures

Derived traits are newly evolved features such as feathers that do not appear in the fossils of common ancestors Ancestral traits are more primitive features such as teeth and tails that do appear in ancestral forms. Computer Art. What are Analogous Colors?. Analogous colors . are side by side on the color wheel – these are the transitional colors. . They are closely related. . Analogous . color . schemes combine several colors . Homologous and Analogous Structures. Need to Know. The difference between homologous and analogous structures and how this relates to evolution.. Convergent evolution. Concept 19.3: Evolution is supported by an overwhelming amount of scientific evidence. Homologous Structures (flowers). 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. .
