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. .

Alexei Fedorov. Recombination is an intrinsic property of nucleic acids and these molecules are susceptible to joining their ends. .. Evolution invented thousands of proteins that assist DNA recombination and became crucial for cell functioning. . 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.. Key Concepts:. What happens during the process of meiosis?.

A . life cycle. of an organism is the generation-to-generation sequence of stages in its reproductive history.. Fossil evidence for evolution. Most evidence of evolution was originally found in fossils. Fossils can preserve the structure of organisms in sedimentary rock if conditions are just right. . One area of evidence of evolution is embryology, the study of embryos. When we compare embryos we can see shared characteristics of organisms throughout their developmental process. . Crossing over . The term crossing over was coined by Morgan.. In crossing over , exchange the chromosomal parts or segments in the non-sister chromatids of homologous chromosomes. . In another words , .
