Something I've been thinking about lately...
27 So God created man in his own image,
in the image of God he created him;
male and female he created them.
28 And God blessed them. And God said to them, “Be fruitful and multiply and fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth.” From Genesis 1 ESV
God also made most animals male and female, but he doesn't mention that in the beginning. But He does make a point of stating that man was created male and female, after saying that they were created in God's image.
