By Patricia Weerakoon The Bible says God created humanity male and female. But the Bible doesn’t give us detailed information about how our bodies develop as either male or female. God did however give us the ability to carefully analyse the world and discover the processes whereby our sex development takes place. In terms of Christian theology, this ability to understand the world fits into the broad category of what the Bible calls ‘wisdom.’ King Solomon, the figurehead of Old Testament wisdom, analysed the world: he “spoke about plant life … animals and birds, reptiles and fish” (1 Kings 4:33).

Different kinds of plants and animals have different reproductive strategies. For example, some plants reproduce asexually, through budding or fragmentation. The new plants are genetically identical to the parent, because no new DNA has been introduced. Humans possess a binary reproductive strategy. I mentioned i...
