What were the first humans like?

The first humans, known as Homo habilis, emerged around 2.4 million years ago and were characterized by their use of simple stone tools. They were small in stature, with a diet that included scavenged meat, fruits, and plants. These early humans lived in small groups and likely communicated using basic vocalizations and gestures. Their survival relied on foraging and adapting to various environments, marking the beginning of human evolution.
