Sexual diversity in nature. I found the arguments made by Dr. Joan Roughgarden quite interesting. The argument I found most interesting was the issue of gender assignment being unstable. Most biologists categorize individuals according to their sex. At birth, one is labeled as either male or female. The sex assignment is based on an individual’s reproductive organs. Roughgarden opposes Darwin’s sexual selection theory arguing that organisms can have both sexes at the same time.
Roughgarden proposes that organisms can have both sexes at the same time or at different times during their lifetime. Roughgarden gives an example of the organisms on coral reefs. According to Roughgarden, about a third of the species living on coral reefs consist of organisms that have both sexes at the same time or at different times during their lifetime. The organisms change from female to male or vice versa. Roughgarden goes ahead to show images of the organisms that have both sexes.
Sexual diversity in nature
I like the argument made by Roughgarden because it questions the common theories of biology. Most biologists argue that one can only have one sex. Organisms are labeled as either male or female at birth. It is interesting to see that the categories of females and males are neither comprehensive nor stable. This explains why some people choose to transition from one sex to the other. In the past few decades, many people have chosen to transition from one sex to the other arguing that they feel more inclined towards the other sex. Also, the argument made explains why some individuals argue that they belong to both sexes. Some people do not transition from one sex to other but prefer to express both sexes from time to time. As Roughgarden explains, it is normal for an individual to change from one sex to the other.
