Why is a robustus named as he is?
After exploring Kromdraai, South Africa, the site where the curious fossils came from, Broom collected many more bones and teeth that together convinced him he had a new species which he named Paranthropus robustus (Paranthropus meaning “beside man”).
What is the meaning of Australopithecus robustus?

Was P robustus a human?
Paranthropus robustus belongs to a group that represents a side branch of the human family tree. The paranthropines are a group of three species that range in time from c. 2.6 mya up to c. 1.2 mya.
Why did Paranthropus go extinct?
Whereas the ancestors of humans were thought to be adaptable generalists, Paranthropus species, which evolved massive teeth and jaws for chewing hard vegetation, were thought to have hit an evolutionary dead end because they were too specialised to adapt to new food sources produced by Africa’s changing climate.
Who found Australopithecus robustus?
The 1959 discovery of a nearly complete cranium by Mary Leakey at Olduvai Gorge, Tanzania, first revealed the presence of a robust australopith in East Africa. The fossil was dated to 1.8 mya, and it was the first African hominin whose age was accurately measured by argon analysis.
Why did Paranthropus robustus go extinct?
What happened robustus?
robustus went through rapid phases of evolution around 2 million years ago. It is thought to be climate change that determined what this hominid would have to eat to survive, and it not only survived but thrived. It almost out-survived our more direct ancestor Homo erectus.
What was the original name for Au africanus robustus?

How did the Australopithecus africanus get its name?
After Prof. Raymond Dart described it and named the species Australopithecus africanus (meaning southern ape of Africa), it took more than 20 years for the scientific community to widely accept Australopithecus as a member of the human family tree. The hunter or the hunted?
