Where did earthworms originally come from?
Origins. Most of the invasive earthworms are European or Asian and came over in soil during the eighteenth century as Europeans began settling the North American continent. The worms were originally transferred through the horticultural trade, probably in the soil bulbs of European plants being carried to the Americas.
Are earthworms native to USA?

Did humans evolve from a worm?
A worm-like creature that burrowed on the seafloor more than 500 million years ago may be key to the evolution of much of the animal kingdom. A multitude of animals, from worms to insects to dinosaurs to humans, are organised around this same basic bilaterian body plan. …
What is the oldest worm ever found?
Scientists have discovered the oldest ever fossil of an ancient worm! The fossil contains earthworms, leeches, ragworms and lugworms from around 514 million years ago, in a time known as the ‘Cambrian period’.
Do Worms multiply?
Worms can’t reproduce just any time. Their bodies undergo changes as they grow older, and at around 90 days old they become old enough to mate. One important thing to take note of is that the larger the worms are, the more often they mate and the more hatchlings their cocoons will produce.
Can you eat earthworms?
The short answer is yes. These squiggly creatures can be eaten raw or cooked, especially for small children who are invariably drawn to earthworms. Not sure why, that’s just the way it is! Worms that are farm raised for eating are fed pest-free food that helps keeps them clean and parasite-free.
Can worms drown?
Earthworms are unable to drown like a human would, and they can even survive several days fully submerged in water. Earthworms often come to the surface to escape moles.
Does water kill earthworms?
So far as I recollect, earthworms are not drowned (or, at any rate, not quickly) if they get into cool, clear, running water—which, presumably, contains a larger amount of dissolved free oxygen than does the rain-water accumulated about dead leaves and deoxidising or “reducing” mud.
