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 researc...
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...
Birds that fly have hollow bones. Beavers have front teeth that never stop growing.Sea otters tie themselves to strands of seaweed at night before they go to sleep. Polar bears have large furry feet and paws.In the summer months artic foxes are brown. In winter they are white. Burmese ...
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 ...
Millions of years ago, that's how our ancestors lived. Over the years, humans adapted to their changing environments by changing how they acted and looked until they became the most sophisticated species on Earth. Humans have hundreds of special features that help us survive, called adaptations,...
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...
This paper reviews evidence from human physiology as to which foods may have been typically consumed by the hominin ancestral lineage up to the advent of anatomically modern humans. Considerable evidence suggests that many common diseases can be prevented by hunter-gatherer diets. Apparently, human nu...
This includes the total utility or value that individuals receive from their consumption of goods and services, as well as the total value of public goods (e.g., education) and common pool resources (e.g., water bodies) that are typically undervalued by individuals. In addition, social ...
Adaption always helps the organism in a good way, it always gives the organism the features it requires in order to survive such as legs for us humans, legs are a necessity to all and that is why we all have them, so we all can survive in our era of time and walk around to do ...
