The American genetic engineering firm Colossal Biosciences recently announced to much fanfare it had “de-extincted” the dire wolf, a canine species that was wiped out around 10,000 years ago. However, the three animals it presented are actually modern grey wolves with some genetic modifications.
Regardless of whether you consider them dire wolves or not, Colossal Bioscience made the interesting claim that it had genetically engineered lost ecological function. This made me ponder what ecological functions are missing from today’s ecosystems as a result of extinctions we have caused.
By ecological function, I am referring to the way all animals have some sort of influence on the ecosystems they inhabit. Honeybees and many other insects pollinate flowering plants, beavers build dams that create ponds and alter the flow rate of streams, elephants knock over trees helping to keep savannas open, and ants and termites shift vast amounts of soil and help decompose plant litter.
