Why are humans so diverse compared to other animals?
The amazing variety of human faces – far greater than that of most other animals – is the result of evolutionary pressure to make each of us unique and easily recognizable, according to a new study by University of California, Berkeley, scientists.

| Just like animals, humans are also driven by instincts. However, we can also reason. | Animals are primarily driven by instincts. |
Why do human beings look different?
Although human beings vary widely in size, colour, and looks, human beings’ genetic makeup is similar. The variations in size, colour and looks result from the different levels of expression of these traits. However, at the genetic level, humans have the same organization. Therefore, humans belong to the same species.
Why are humans less genetically diverse?
Human genetic diversity decreases in native populations with migratory distance from Africa, and this is thought to be due to bottlenecks during human migration, which are events that temporarily reduce population size.
Are humans more genetically diverse than other animals?
Perhaps the most widely cited statistic about human genetic diversity is that any two humans differ, on average, at about 1 in 1,000 DNA base pairs (0.1\%). Human genetic diversity is substantially lower than that of many other species, including our nearest evolutionary relative, the chimpanzee.
What are the biggest differences between animals and humans?
The biggest difference between humans and animals is that humans are driven by reason and logic. They can engage in intellectual activities. Animals, on the other hand, are completely driven by instincts.
Why do humans resemble animals?
Years of research suggest humans see certain features in animals (e.g., big eyes or round cheeks) that we typically associate with baby humans. Our brains associate human baby features with cuteness, qualities which we then project onto pets like cats and dogs. This phenomenon is known as “baby schema.”
Why are humans flat faces?
While early human relatives like Neanderthals are typically depicted as having heavy brows, large noses and thick skulls, modern humans have far more delicate, flatter features. Modern humans, by comparison, actually reabsorb bone from the front of their face around the upper jaw, leading to a much flatter skull shape.
