R&B Vocal Groups (161 words) |
 | This section is devoted to the classic RandB groups that stand out as innovators and true exponents of this musical style. |
 | As the music evolved in the early 1950's, groups developed styles representative of the areas where they lived in the United States. |
 | Therefore, group biographies have been separated by four regions of the United States. |
| Jarvis Lab -- Evolution of Brain Stuctures for Vocal Learning (507 words) |
 | It is known to be present in only 6 groups of animals: 3 groups of birds (parrots, songbirds, and hummingbirds) and 3 groups of mammals (bats, cetaceans[whales/dolphins], and humans). |
 | Vocal learning is the ability to imitate sounds that you hear, such as a human or a parrot imitating the sound "sit". |
 | If according to the current dominant hypothesis, vocal learning evolved independently in all 6 vocal learning groups within the past 65 million years, then the striking similarities in brain structures of at least the 3 avian groups suggest that there a strong epigenetic constraints on how vocal learning can evolve. |
