Final answer:
The Taung child implied a scenario of early hominid bipedalism and upright posture, which conflicted with the initially believed characteristics of the Piltdown remains.
Step-by-step explanation:
The Taung child and the Piltdown remains were two significant fossil discoveries in the early twentieth century that provided insights into human evolution. The Taung child, belonging to the species Australopithecus africanus, implied a scenario of early hominid bipedalism and upright posture. This implication conflicted with the Piltdown remains, which were later revealed to be a hoax and initially suggested a human ancestor with a large brain and ape-like jaw. The Taung child's discovery challenged the idea of human evolution by presenting evidence of bipedalism, while the Piltdown remains created confusion with their deceptive characteristics.
