Your Nose Knows Evolution – Do You?

Olfaction is one of the least understood senses but has played a vital role in the evolution of vertebrates. Basic survival behaviors such as foraging, communicating, recalling memory, and reproduction are often dependent on a protruding-facial structure that we too often ignore.

Kansas City, Missouri - The vomeronasal organ (VNO) is one of evolution's most direct enforcers. From its niche within the nose in most land-based vertebrates, it detects pheromones and triggers corresponding basic-instinct behavior...

Forage longer for berries, study on age-related memory decline suggests

Academics / General Science : Science Daily (2 years ago)

Like birds which stop foraging too early on a berry-laden bush, a new study suggests older people struggle to recall items because they flit too often between ‘patches’ in their memories.

Avian Olfactory Receptor Gene Repertoires: Evidence For A Well-developed Sense Of Smell In Birds?

Health : Medical News Today (7 years ago)

Avian olfaction is poorly understood: birds are widely regarded as relying primarily on visual and auditory inputs. Among vertebrates, the sense of smell is mediated by olfactory receptors (ORs).
