How did Paranthropus boisei get its name?

What did Paranthropus boisei eat?

Did Paranthropus use tools?
While scientists have not found any stone tools associated with Paranthropus robustus fossils, experiments and microscopic studies of bone fragments show that these early humans probably used bones as tools to dig in termite mounds. Through repeated use, the ends of these tools became rounded and polished.

Was Paranthropus boisei a human ancestor?
boisei skull KNM-ER 406 was demonstrated to have been contemporaneous with the H. ergaster skull KNM ER 3733, which is generally taken to show that Paranthropus was a sister taxon to Homo, both developing from some Australopithecus species, which at the time only included A.

Reconstructed replica of “Nutcracker Man,” a 1.75-million-year-old Paranthropus boisei skull found in 1959 by archaeologist Mary Leakey at Olduvai Gorge, Tanzania. The skull was originally classified as Zinjanthropus boisei by Louis Leakey. Approximate time ranges of sites yielding australopith fossils.
Are there any other hominids alive today?
Some recently extinct species in the genus Homo are only recently discovered and do not as yet have consensus binomial names (see Denisova hominin and Red Deer Cave people). Since the beginning of the Holocene, it is likely that Homo sapiens (anatomically modern humans) has been the only extant species of Homo.
Are australopithecines Hominins?
The genus Australopithecus is a collection of hominin species that span the time period from 4.18 to about 2 million years ago. Australopiths were terrestrial bipedal ape-like animals that had large chewing teeth with thick enamel caps, but whose brains were only very slightly larger than those of great apes.
What were the first hominins?
