By analyzing genomic data we can detect and use the footprints that adaptive (positive) natural selection leaves in our genome to identify human adaptations at different timescales, as well as the resulting phenotypical traits that in current populations define us as humans. Although genomics has ...
A2010Naturestudy showedthat these nerve receptors work by using the same nerve cell proteins that humans use to detect chemical irritants from sources as diverse as tear gas and chopped onions. In the snakes these 'wasabi receptors’ have evolved to detect heat.More recent research...
Like humans, killer whales have colonized a range of different __8__ across the globe, occupying every ocean basin on the planet with an empire that __9__ from pole to pole. As such, different populations of killer whales have had to learn different hunting techniques in order to gain t...
In myriad species, including humans, females experience dramatic shifts in fertility levels. Given that conception is most likely to occur during periods of peak fertility, evolutionary theories suggest that males possess adaptive attunements to those shifting fertility levels. While male adaptations to ...
Overall Weakest Creature: Humans. What are two human adaptations? Ourbipedalism (ability to walk on two feet), opposable thumbs (which can touch the fingers of the same hand), and complex brain (which controls everything we do) are three adaptations (special features that help us survive) ...
Directed by Matt Johnson and starring Glenn Howerton, Jay Baruchel, Rich Sommer, Michael Ironside, and Johnson, the exaggerated story about the one-time must-have piece of technology is a darkly funny tale that both critics and audiences found engaging, though most execs were unamused. Howerton...
Criminal Cost-inflicting Behaviors The criminal cost-inflicting strategies that humans employ manifest in many dif- ferent guises, including robbery, assault, rape, and murder. Many hostile human activities have been proposed to be the result of psychological adaptations. Re- searchers have found ...
weaned before winter, when four to six months old. Malnutrition rather thanpredationaccounts for manylambdeaths, as lactating mothers may reduce milk production in order to store fat against the coming cold. Lambs that gain more weight survive winter better and have higher lifetime reproductive ...

Animals like the jackrabbit have very large ears that have a network of blood vessels. When these animals rest in the shade, their enormous ears dissipate the excess heat from their bodies. Check this video to know more about Adaptation in plants and animals in the Desert: ...
