Question 1 • TPS EdX Biology
A single dichotomous key might be incomplete or outdated, so failing to identify the insect with that key alone does not prove it is a new species. If several other thorough, up-to-date keys also fail to identify it, that is stronger evidence that it may not match any known species. Damage or changes in diet could affect the insect’s appearance or behavior without making it a new species.
