Final answer:
The pattern of ridges for classification belongs to the subject of anthropology and is related to the consistent and unique identification of individuals, demonstrating the lack of scientific basis for racial categorization.
Step-by-step explanation:
The unique and unchanged general pattern of ridges which allows for classification is a subject pertaining to anthropology. When looking at the ridges, such as those present in a fingerprint, one can determine characteristics that remain consistent across times, such as personal identification. This concept is intimately related with the study of humans, both physically and culturally, and fits within the broader discipline of anthropology. However, it's important to note that the classification based on physical characteristics, such as skin color or fingerprint patterns, does not align with the notion of scientifically valid racial categories. Biological anthropology has shown that there is substantial variation within so-called racial groups, and that visible traits like skin color and invisible genetic markers like blood type demonstrate that there are no discrete racial categories in humans.
