Practice question · Multiple choice
Lucy walked upright with a brain of about 400 cc, roughly a chimpanzee’s. Why does that ordering matter for how hominisation is explained?
Hints
- Ask which trait appears first in the fossil record.
- A cause cannot arrive after its effect.
Show the answer
A. Because bipedality came millions of years before big brains
Why
Sequence constrains causation. The "brain first" story was intuitive and is simply excluded by the dates, which is why explanations now begin with locomotion, diet and habitat.
