The Table shows information about three fossils and modern humans.
Table
| Fossil | Age in millions of years | Estimated brain volume in cm3\text{cm}^3cm3 | Estimated height in cm |
|---|---|---|---|
| Ardi | 4.4 | 350 | 120 |
| Lucy | 3.2 | 450 | 107 |
| Turkana Boy | 1.6 | 900 | 160 |
| modern human | 0 | 1350 | 170 |
Describe the trend in brain volume shown in the Table.
Calculate the percentage increase in brain volume from Lucy to Turkana Boy.
Turkana Boy had long legs and short arms.
Explain what this suggests about how Turkana Boy moved.
A student said:
"Turkana Boy is more like a modern human than Lucy is."
Give two pieces of evidence from the Table that support this statement.
40 exam-style questions on Edexcel GCSE Biology 4.2 Evidence for evolution and classification, covering 4.2.1 Fossil evidence for human evolution, 4.2.2 Stone tool evidence for human evolution, 4.2.3 Pentadactyl limb as evidence, and 4.2.4 Three domains classification. Each one has a worked solution and a mark scheme showing where the marks go.
