Which option gives the correct cause-and-effect relationship for The development of understanding of genetics and evolution, Fossils: students must describe fossils as preserved traces such as footprints, burrows and rootlet traces.
- A.Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Fossils because students must describe fossils as preserved traces such as footprints, burrows and rootlet traces.
- B.Reversed cause: Treating DNA as if it always means one gene. This would blur DNA vs genes instead of testing Fossils.
- C.Missing link: Calling a gene a whole chromosome. This misses the objective focus on describe fossils as preserved traces such as footprints, burrows and rootlet traces.
- D.Different process: It moves into a neighbouring Unit 4.6 idea rather than The development of understanding of genetics and evolution / Fossils.
