The human body readily responds to changing environmental stresses in a variety of biological and cultural ways . We can acclimatize to a wide range of temperature and humidity. ... This ability to rapidly adapt to varying environmental conditions has made it possible for us to survive in most regions of the world.
What are some examples of human adaptations?
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.

Are humans still evolving?
It is selection pressure that drives natural selection (‘survival of the fittest’) and it is how we evolved into the species we are today. ... Genetic studies have demonstrated that humans are still evolving .
Where do humans evolve from?
Humans first evolved in Africa , and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
Who was the first human on earth?
One of the earliest known humans is Homo habilis
Can humans evolve to breathe underwater?
Scientists have discovered a way for humans to potentially breathe underwater by merging our DNA with that of algae . ... The real-life version however could work on a more fundamental level and change our DNA so that we are more like algae, which actually give off oxygen even though they are on the sea bed.
How fast are humans evolving?
A study by anthropologists John Hawks, Henry Harpending, Gregory Cochran, and colleagues suggests that human evolution has sped up significantly since the beginning of the Holocene, at an estimated pace of around 100 times faster than during the Paleolithic , primarily in the farming populations of Eurasia.
How did life start on Earth?
Although the exact process by which life formed on Earth is not well understood, the origin of life requires the presence of carbon-based molecules, liquid water and an energy source . ... Life on Earth began at the end of this period called the late heavy bombardment, some 3.8 billion years ago.
What color was the first human?
These early humans probably had pale skin , much like humans’ closest living relative, the chimpanzee, which is white under its fur. Around 1.2 million to 1.8 million years ago, early Homo sapiens evolved dark skin.
Do humans come from monkeys?
Humans and monkeys are both primates . But humans are not descended from monkeys or any other primate living today. We do share a common ape ancestor with chimpanzees. ... But humans and chimpanzees evolved differently from that same ancestor.
When was Adam and Eve born?
They used these variations to create a more reliable molecular clock and found that Adam lived between 120,000 and 156,000 years ago . A comparable analysis of the same men’s mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago 1 .
Who came first dinosaurs or Adam and Eve?
Dinny’s new owners, pointing to the Book of Genesis, contend that most dinosaurs arrived on Earth the same day as Adam and Eve , some 6,000 years ago, and later marched two by two onto Noah’s Ark.
What animal did humans evolve from?
Humans are one type of several living species of great apes . Humans evolved alongside orangutans, chimpanzees, bonobos, and gorillas. All of these share a common ancestor before about 7 million years ago. Learn more about apes.
Can humans evolve to be stronger?
While there is no proof that modern humans have become physically weaker than past generations of humans, inferences from such things as bone robusticity and long bone cortical thickness can be made as a representation of physical strength.
Can humans evolve gills?
Artificial gills are unproven conceptualised devices to allow a human to be able to take in oxygen from surrounding water. ... As a practical matter, therefore, it is unclear that a usable artificial gill could be created because of the large amount of oxygen a human would need extracted from the water.
