Arbuscular mycorrhizal fungi (AMF) nodules, found on the roots of over 80% of all vascular plant species, played a crucial role in facilitating the rapid colonization of the continental landmasses by vascular plants. Without this symbiotic and widespread relationship between AMF and vascular plants, neither soulish animals (birds and mammals) nor human beings would thrive on Earth. Both would lack the necessary supply of food and nutrients. The creation and maintenance of large-bodied soulish animals described in Genesis 1:21 and of humans in Genesis 1:26–27 would be impossible without the symbiotic connection between vascular plants and AMF being established first.
