According to White & Batty’s recent correlations, you may already have.
Ever wonder why some people are exceedingly good at being with someone and others struggle? Most would blame it on personality, upbringing, hormones. But what if you found out it was out of your control? What if you found out you were predisposed from birth to be monogamous or not!?
Scientists at Emory University have begun to study Prairie voles and have come out with some amazing discoveries! The reason they studied prairie voles is they are a monogamous rodent! A similar species though the meadow voles are super promiscuous and love to be in the end alone. Read the rest of this entry
The barn owl (Tyto alba) has been said to be one of the most successful nocturnal predatory birds that exist in our world today. As adults, barn owls rarely miss their target prey. They owe this to their finely tuned auditory system. Owls combine excellent hearing with visual tracking to perfectly locate prey and maximize their chances of successful capture (http://www.allaboutbirds.org). Their auditory tracking system functions based on several key features of barn owl morphology. The first is that barn owls possess asymmetrically shaped ears. This means that the owl’s left ear points downward and the right ear points upward. A sound that appears louder in amplitude on the right side of the owl is interpreted as being higher in elevation than a sound that appears louder in amplitude on the left side of the owl. This helps the owl discern moving target’s elevations. The second key feature is the owl’s facial disk. Barn owls are known for having a heart shaped face. This facial disk acts like the pinna on humans and helps the owl to amplify sounds. (Koppl et al. 2007) The last key feature is the owl’s ability to detect timing differences in sounds. The owl’s midbrain can process the differences in arrival times of a sound between one ear and the other. The owl can then use this information to help them direct their head towards the prey item.
