This article discusses the reasons why humans are not covered in hair like other primates. It suggests that our ancestors lost their thick, hairy coats when they began hunting on hot grasslands, as fur would have caused them to overheat. Additionally, hair is metabolically expensive to produce, and humans found cheaper alternatives, such as wearing animal pelts or using plant fibers. The article also mentions the hypothesis of our semi-aquatic evolution, which explains why humans have certain traits and adaptations. However, it emphasizes that all ideas about evolution are speculative and should be taken with caution. [Extracted from the article] |
