Worked Solution & Example Answer:Scientists investigated fossils of four different groups of mammals - Edexcel - GCSE Biology - Question 3 - 2016 - Paper 1
Step 1
Which statement is supported by the information in the diagram?
Answer
To determine which statement is supported by the diagram, we must analyze the population sizes depicted for each group over the specified time frame.
- A is incorrect; group A existed earlier than 10 million years ago based on the diagram.
- B is likely correct; the diagram indicates that Group B had the largest estimated population around 15 million years ago.
- C is incorrect; the diagram shows that Group C has an earlier existence than the most recent group.
- D is inaccurate; Group D does not show extinction at 10 million years according to the provided population data.
Thus, the correct answer would be B: Group B contained the largest group of mammals 15 million years ago.
