It would be really cool if horses could fly.
But the scientific method doesn't accept "it would
be cool" as evidence. If there had been a horse
with wings we might see fossils of one. Fossils
are basically bones that have turned into stone,
so they last much, much longer than bone. We have
many fossils of horses and their ancestors. No one
has ever found fossils of horses with wings. That
is not proof that they never existed. Maybe they
never got fossilized. Maybe the fossils are out
there but we haven't found them yet.
Another important question is whether a horse
with wings could fly.Unfortunately, what we know
from physics, which tells us about energyand
matter (stuff), and biology, which tells us about
living things, tells us horses couldn't fly even
if they had wings.
Let's look as some
kinds of flying animals. Lots of insects fly.
Most birds fly. The only true flying mammals are
bats (flying squirrels just glide). Things that
fly must be very light. They have thin bones. A
bird's feathers usually weight more than its
bones. They eathigh-quality food that doesn't take
long to digest.
Horses have large heavy
bones with heavy hooves. Now, you could imagine a
horse with light bones, but they wouldn't be
strong enough to allow the horse to run.
Racehorses are bred to have light bones and they
sometimes break when they run. Even racehorses
are really heavy.
Horses eat grasses, and
then take a long time to digest it, so they
haveheavy food. Geese are one of the few grazing
birds, but they don't eat much during their flying
season and don't fly much during their eating
Can we prove that Pegasus never
existed? No, but it doesn't seem
What other evidence would convince
you that Pegasus did or didn't exist? Looking at
flying animals may give you some clues.Thanks
