Certain species of wild oats have a special seed dispersal system that looks as if the seeds are walking on the ground looking for suitable soil to take root in.
Modern-day oats (Avena sativa) have been drastically altered through domestication and are entirely dependent on humans for their survival. Not only do they need to be drilled into the soil, but the seeds remain attached to the panicle to make them easier to harvest and minimize seed losses. Wild oats, on the other hand, are a completely different story. They have evolved highly specialized anatomical features that actually assist the spikelets housing the seeds to move on the ground in search of suitable rooting soil. This amazing ability has won the plants several nicknames, including “Animated Oats” and “Animal Oats”.
