Bright bird plumage resulted from natural, sexual selection
Darwin hypothesized that bird color differences resulted from sexual selection. Wallace disagreed. A study shows that both were right after all.
- Neuroscience
Our taste in music may age out of harmony
Age-related hearing loss may be more than just the highest notes. The brain may also lose the ability to tell consonance from dissonance, a new study shows.
