Final answer:
The seven species mentioned are Sahelanthropus, Orrorin, Ardipithecus, Australopithecus, Kenyanthropus, Paranthropus, and Homo, which are all part of the human evolutionary lineage.
Step-by-step explanation:
The names of the seven species mentioned are: Sahelanthropus, Orrorin, Ardipithecus, Australopithecus, Kenyanthropus, Paranthropus, and Homo. These represent different genera or species in the evolution of hominins, each contributing to our understanding of human ancestry and evolution. Australopithecus species like Australopithecus afarensis, Australopithecus bahrelghazali, Australopithecus garhi, and Australopithecus africanus were important early hominins known for their bipedality and brain development.
The genus Paranthropus represents robust species such as Paranthropus robustus, P. boisei, and P. aethiopicus, which were not directly ancestral to humans but were part of the hominin tree. Homo refers to our own genus, which includes modern humans and species like Homo erectus.
