Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower.
The area that needs a high sensitivity like the palm of the <span>hands(especially the fingertips), face</span>, and tongue should be the one with lowest two-point discrimination.
In this report, a<span>nterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm.

A biologist would most likely concentrate on homologous features to find and analyse an evolutionary relationship between two species, finding homologous traits between species might help biologists to understand the evolution of animals, whereas concentrating on analogous features might help to compare the evolution of different species. Hope this helped!
