Final answer:
The statement is false; Sahelanthropus tchadensis, not to be confused with Piltdown Man, was discovered in Chad in 2001 and has important implications for human evolutionary research.
Step-by-step explanation:
The statement 'Sahelanthropus was found in England in 1920 and is known as Piltdown Man' is false. Piltdown Man was a hoax based on fraudulent findings presented in 1912 in England, whereas Sahelanthropus tchadensis, often referred to as 'Toumai', is a genuine fossil species discovered in Chad in 2001 by a team led by Michel Brunet. Sahelanthropus lived nearly seven million years ago and is considered by some researchers to be a critical species for understanding human evolution, potentially representing the last common ancestor of humans and chimpanzees.
The discovery of Sahelanthropus is significant because it adds to the complex mosaic of early hominins that includes other species like Australopithecus africanus and Australopithecus sediba. Unlike Piltdown Man, Sahelanthropus provides valuable insights into the evolutionary lineage that led to modern humans, with features suggesting it lived right at the divergence time between humans and chimpanzees.
