Question 20
H

A student makes three claims about the development of evolutionary theory.

  1. Wallace's independent work contributed to Darwin publishing his ideas.
  2. Discovering inherited units provided a mechanism that Darwin could not originally explain.
  3. Fossil gaps mean that observed antibiotic resistance cannot support natural selection.

Which evaluation is correct?

[1]
A

Claims 1 and 3 are supported; claim 2 confuses inheritance with acquired characteristics.

B

Claims 1 and 2 are supported; claim 3 confuses incomplete evidence with contradictory evidence.

C

Claims 2 and 3 are supported; claim 1 confuses independent discovery with joint publication.

D

Claims 1 and 2 are supported; claim 3 confuses individual survival with inherited variation.
