Here are some examples of some prominent scientists and archaeologists who have called Homo habilis and Homo erectus humans:
Louis Leakey: In 1975, Leakey called Homo habilis "the first human." Leakey argued that Homo habilis was the first species to make and use stone tools, which he saw as a defining characteristic of humanity.
Richard Leakey: Richard Leakey, Louis Leakey's son, also called Homo habilis "the first human." In his book "The Making of Mankind," Leakey wrote that Homo habilis was "the first member of our own genus, Homo."
Donald Johanson: Donald Johanson, the discoverer of the famous Lucy skeleton, has also called Homo habilis "the first human." In his book "Lucy: The Beginnings of Humankind," Johanson wrote that Homo habilis was "the first species that we can confidently call human."
Mary Leakey: Mary Leakey, Louis Leakey's wife, has also called Homo habilis "the first human." In her book "Olduvai Gorge," Mary Leakey wrote that Homo habilis was "the first species in the genus Homo."
Tim White: Tim White, an American paleoanthropologist, has also called Homo habilis "the first human." In his book "Pleistocene Hominid Evolution in East Africa," White wrote that Homo habilis was "the first species in the genus Homo to have a brain size comparable to that of modern humans."
