    While it’s not the reason we have 2 sexes, there is an evolutionary reason for 2 partners to make an offspring, which is likely a big contributing factor

    While asexual reproduction is easier, the downside is that the child is almost an exact genetic match of the parent. There’s a lot of reasons why this is not ideal (I don’t remember them lol, its complicated), so having 2 organisms mix their genes to create a genetically unique offspring is extremely advantageous. Having 2 sexes is likely easier than doing this with a unisex species, but as another commenter pointed out: evolution doesn’t make sense, it just does what works.
