What is an example of adaptation in humans?
Humans exhibit a number of biological adaptations to the great variety of environments they occupy. The best example of human genetic adaptation to climate is skin color, which likely evolved as an adaptation to ultraviolet radiation.
What is an example of evolutionary adaptation?
One of the textbook examples of evolutionary adaptation is the long-necked giraffe. The evolution of the giraffe’s long neck occurred so that the animal could reach leaves in taller trees. But the story of giraffe’s long necks is even more complex than that.
What are two examples of adaptations humans have evolved?
Human traits that emerged recently include the ability to free-dive for long periods of time, adaptations for living in high altitudes where oxygen concentrations are low, resistance to contagious diseases (such as malaria), light skin, blue eyes, lactase persistence (or the ability to digest milk after weaning), the …

What evolutionary advantages do humans have?
We lead an energy-intensive, communication-driven, information-rich way of life, and it was the evolution of middle age that supported this. For example, hunter-gatherer societies often have complex and difficult techniques for finding and processing food that take a long time to learn.
What are 3 adaptations humans have?
Our bipedalism (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) that have allowed us to live in so many different climates and habitats.
What is one human adaptation that helps us to survive and reproduce?
What are 3 physical adaptations?
Physical adaptations do not develop during an individual animal’s life, but over many generations. The shape of a bird’s beak, the color of a mammal’s fur, the thickness or thinness of the fur, the shape of the nose or ears are all examples of physical adaptations which help different animals survive.
How do adaptations relate to evolutionary change?
Adaptation is evolution by natural selection. However keep in mind that the word is used in two related, but different ways. You’re using it here to describe a process: “adaptation occurs over time because the frequency of phenotypes in a population changes as a result of differential reproduction.”.
Why are adaptations important to evolutionary?
Adaptation is related to biological fitness , which governs the rate of evolution as measured by change in gene frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects.
Are mutations good examples of adaptations?
A very small percentage of all mutations actually have a positive effect. These mutations lead to new versions of proteins that help an individual better adapt to changes in his or her environment. For example, a beneficial mutation could result in a protein that protects an individual and future generations from a new strain of bacteria.
Which is the best description of an adaptation?
An adaptation is a physical or behavioral characteristic that has developed to allow an organism to better survive in its environment. Adaptations are the result of evolution and may occur when a gene mutates, or changes by accident.
