A scientist makes the argument that two species of butterflies should be considered the same species
because they have similar DNA, similar wing length, and similar migration patterns. The butterflies also
have variations in colour patterns and different mating seasons.
Which piece of evidence would most go against the scientist's argument and suggest that the butterflies
are actually different species?
1. The butterflies have similar wing structure.
2. The butterflies have different mating seasons.
3. The butterflies have similar migration patterns.
4. The butterflies have variations in colour patterns.
