Surely some mad scientist has been hard at work trying to splice animal and human genes in order to create an army of ravenous rabbit men, or lazy three toed sloth people, but nothing currently known to science looks as far out as these images from the 1930s that imagine what human-animal hybrids might look like.
Mantis man is a very efficient farmer, and one heck of a climber, while firefly man is able to picnic in the middle of the night, which may be a dream come true for a nocturnal lover of outdoor dining. These fantastic images come to us courtesy of artist Lucian Rudaux, who would have been so disappointed to find out the future is devoid of the insect men and flying cars he so loved to draw for various publications in the early 20th century.
This series in particular was envisioned by his good friend Professor Rene Thevenin, who really believed scientific advancement would have made these monstrosities a possibility by the 21st century. Lucky us they're still well outside the realm of possibility!
