Scientists used to think that only humans used tools and language. But when chimpanzees were spotted making tools, and gorillas and orangutams learned sign language, the gap between humans and other primates narrowed. The scientists discovered that chimp and human DNA s nearly 99% alike. We’re more alike than different.
All primates use some form of communication, but humans are the only primates that communicate across the globe.
Hands are one way humans resemble other primates. With some primates we also share the ability to make tools, learn through discovery and pass on new-found knowledge.
What makes us different? humans walk upright, communicate with words, and practice a variety of beliefs and religions.
