what is an example of a human adaptation

Neuroplasticity is seen as an adaptation that helps humans to adapt to new stimuli, especially through motor functions in musically inclined people, as well as several other hand-eye coordination activities. Genetic adaptations. Adaptation is an observable fact of life accepted by philosophers and natural historians from ancient times, independently of their views on evolution, but their explanations differed. i.e. Sign up for a daily selection of our best stories — based on your reading preferences. Another example of a genetic solution to an environmental stress is our ability to produce sweat as an aid in cooling our bodies in hot environments. An adaptation is a feature that is common in a population because it provides some improved function. science. "The evolution of the brain is the most obvious example of how we evolve to adapt," he explained. For example, a species living in water that suddenly becomes more acidic might adapt by slowly shifting its own body chemistry. Humans in Nepal have developed a gene that can raise the number of platelets in their blood, so they can survive low oxygen levels atop mountains. hyperplasia. Among humans, developmental adjustments result from both natural environmental pressures and cultural practices. Some adaptations take place over the course of generations of individuals. An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts. Genetics. Cultural and technological changes are among the most complex adaptations humans use. Human populations in different parts of the world exhibit differences in traits, which may be adaptations to their local environments. Log in here for access. That's just hard nourishment. However, there is another side to the picture. Millions of years ago, that's how our ancestors lived. The reason humans have been able to survive for millions of years in many different environments, is because of this wonderful part of our body. Understanding the genetic basis of adaptation of skin color in various populations has many implications in human evolution and medicine. Recent Human Adaptations. Humans have hundreds of special features that help us survive, called adaptations, but we're only going to look at a few of the most important that really set us … Heritable characteristics that favour tolerance and survival in a particular total environment. Compared to overall body size, humans have the largest brain of any mammal. Over a vast number of generations they have genetically changed to match the thin air of the extremely high altitudes and the cold temperatures. This type of adaptation may be driven by either a change to the environment or the behavior of another species. 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. An example of this is the body's ability to add and shed fat in response to a changing diet. The many different parts of our brain make it possible to solve problems and develop language and talents. since. Humans have biological plasticity, or an ability to adapt biologically to our environment. Two doses can make me sick. growth by virtue of an increase in intercellular material. Bipedalism leaves our hands open to hold tools and grab food off of trees or bushes. It would be pretty difficult, wouldn't it? This tutorial describes three examples of recent human adaptations: lactose tolerance, sickle cell disease, and bitter taste perception.

C. Human adaptation regarding food takes place through three primary mechanisms; genotypic, phenotype, and socio-cultural changes.
