Many of the following early humans that mixed with each other over time:
* The 7 main levels of biological classification for humans, from broad to specific, are Domain (Eukaryota), Kingdom (Animalia), Phylum (Chordata), Class (Mammalia), Order (Primata), Family (Hominidae), Genus (Homo), and Species (sapiens), with the scientific name being Homo sapiens. These ranks show humans are complex eukaryotes, animals with backbones, hair, and live birth, belonging to the primate order and the human family (Hominidae).
Here's a breakdown of each level:
Domain: Eukaryota (cells with a nucleus).
Kingdom: Animalia (multicellular, ingest food).
Phylum: Chordata (have a dorsal nerve cord, backbone).
Class: Mammalia (warm-blooded, have hair, produce milk).
Order: Primata (grasping hands, large brains, often upright).
Family: Hominidae (great apes: humans, chimps, gorillas, orangutans).
Genus: Homo (human-like, large brains, tool use).
Species: sapiens (Homo sapiens, meaning "wise man").
What are the 7 other species of humans?
Apart from our species, the gallery features eight other kinds of human: Homo habilis, Homo rudolfensis, Homo erectus, Homo antecessor, Homo heidelbergensis, Homo floresiensis (nicknamed 'the hobbit'), and the Homo naledi.
