The stages of human development can be culturally defined in addition to biologically defined. The biological stages describe when things grown in develop in a human throughout their life span. These stages are for the most part clear and stay pretty true to the ages in when things happen. However in different cultures, they will care for their children in different ways. In different cultures, they experience different upbringings; doing certain things differently because of the way their culture lives their life. Here's a link to an article I found talking about this concept.

This used to be the way in which people distinguished between who people were and where they came from. However now it symbolizes the misperceptions that many Americans and others around the world have about human variation. We have now discounted the idea of race as a biologically valid concept. Franz Boas wanted to challenge this approach to human biological variation. Specifically, he studied the notion that head shape and other "so-called racial markers" were unchanging throughout time. Boas and his researchers studied some 18,000 immigrant families and calculated the ratio of head length to head breadth. Results revealed that children's heads differed from that of their parents. The difference wasn't big but it was enough to be seen by the researchers and calculated. R.C. Lewontin tested the race concept by studying global genetic variation. After focusing on different areas, he found that the grouped up races of the time only accounted for an incredibly slim percent of the genetic diversity. In addition since this study, more studies have been conducted and have reached the same conclusion. Researchers have since discovered that people don't belong to races but to cline's - which allows for much more variation in different
