Final answer:
The statement all primates are primarily quadrupedal is false; species like Homo erectus were bipedal, and humans are not superior in all ways to other primates.
Step-by-step explanation:
The statement that all primates are primarily quadrupedal is False. Apes, including humans, are capable of bipedal locomotion and have morphological features that facilitate it. For example, Homo erectus, which is indeed in the same family as modern humans, was known to walk upright. The discovery of Homo naledi was significant because it added to our understanding of hominin diversity and our evolutionary history. Homo naledi exhibited a mixture of primitive and modern traits, underscoring the complexity of human evolution. The claim that humans are superior in all ways to other primates is False. While humans may exhibit advanced cognitive abilities and technology use, 'superiority' is a subjective term, and each species of primate is well-adapted to its environment.
