"...Blessed is the child you will bear." This is present tense, not future. In other words, the child (Jesus) was present at that moment and was recognized by Elizabeth.
"And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good."
Genesis 1:25 KJV
This can be seen in cellular and reproductive science.
When cells reproduce, they undergo mitosis. Mitosis always results in sister cells that are of the same species or kind as the mother cell. This means that fish cells will only reproduce and create more fish cells; human cells will reproduce and only create more human cells.
