  2. Vibrating Heads • Males shake their feathers • Females heads resonant • Spindly feathers on female heads pick up frequencies

  3. Peacock • These tiny feathers would also likely cause the female to feel the sound frequency as well. • This is unique behavior only really seen in the animal kingdom through katydids with ear receptors that tune into a potential mate’s frequencies. This brings a new level to love being transmitted on a specific frequency. • These frequencies are picked up via a vibrometer that uses laser Doppler tech to measure the frequencies. • It is thought that some feathered dinosaurs may have had similar qualities. • New Scientist

  4. Genetic Markers • Knowing genetic predispositions • leads to healthy lifestyles • Lasted longer than 18 months

  5. Genes • Elisabeth Widen at University of Helsinki performed this research with her colleagues showing that people who found out about their heart disease risk altered their lifestyles and stuck to it for greater than 18 months. Most experts say people change habits for 6 months then resort back to previous behavior. This study suggests that people when given their genetic risk, will alter their behavior to lower the environmental factors. The study involved 1022 people in Finland aged 45-65 found that 1/3 of the individuals with at least a 10% risk of developing heart disease changed their habits. 17% of smokers quit and 14% lost on average 3 kilos of weight. • Knowledge is indeed power.

  6. Animals Turn Dark • Mammals are reverting to nocturnal habits • Meta analysis shows human presence to be a factor • Cities, hiking trials, roads, settlements

  7. Mammals • Mammals are increasing in numbers in nocturnal activities. Mammals only became active during the day after the destruction of the dinosaurs. Mammals still have some qualities present from those ancient days to help them work in the evening. Kaitlyn Gaynor and her associates performed this meta analysis and found that mammals were increasingly more active in the evening in areas where there was a human presence as opposed to areas with little to no human presence. This analysis involved 76 studies of 62 mammals around the world. One example involves the sun bear in Indonesia where 19% of active customarily happens in the evening. In higher human populated areas, 90% of sun bear activity happens at night. Similar numbers are seen with lion activity in Tanzania. With fewer spaces for wild animals to be away from people, many species are resorting to nocturnal activities to avoid humans. This in turn could affect other nocturnal animals in regard to resources and interactions. This is expected to be a strong force in natural selection.
