How Humans Have Forced Animals To Evolve

How Humans Have Forced Animals To Evolve Whether you believe in it or not, there’s
no doubt that humans themselves have had a hand in evolution over the years. Whether it be because of our hunting, or because
we want cuter pets, we have a tendency to twist and create forced evolution so that
the animals that surround us bend to our will. Today, we’ll be looking at some dogs and other
animals that have been forced to evolve because of human influence. But first, before we begin this video, don’t

at the end of the video! Let’s start with some dogs that have been
forcefully changed or evolved because of humans. Over time, breeders have selectively raised
dogs in order to have specific physical and mental traits to appeal to future pet owners. Some of these traits, which breeders will
attempt to manipulate, include Demeanor, The texture of their coats, Size and various other
features that we have forced dogs to evolve over the years. Unfortunately, designing breeds for a more
desirable outcome can have negative effects on the dog itself. However, the risk of creating health burdens
hasn’t stopped the intentional breeding of unhealthy dogs. Reviewing pictures of breeds from over 100
years ago in the 1915 book, Breeds of All Nations by W.E. Mason, it’s clear to see
how breeds have visibly changed. According to SCIENCE OF DOGS, they haven’t
just changed visually, but they’ve grown to become more unhealthy. Here are 8 dog breeds and how they’ve changed
after a century of intensive breeding. 1. The Bull Terrier: These previously athletic
dogs have been improperly bred over the years, which has caused a drastic change in appearance
and health. Due to the manipulated changes this breed
has experienced, modern bull terriers often suffer from dental problems stemming from
the fact that they have too many teeth. Mental deficiencies have also been a result
of improper breeding, including compulsive tail-chasing. 2. The German Shepherd: 100 years ago, this breed
was considered to be a medium sized dog and had many notable features. These have become distorted through intensive
selective breeding. German Shepherds of today are a whopping 30
pounds heavier, developed sloping backs, and a barrel-chest. Due to these changes, the breed often suffers
leg and hip problems with age. 3. The Pug: pugs are a very distinguishable breed,
but they’ve only become this recognizable due to breeders continually attempting to
exaggerate the dog’s features. These forced changes have resulted in a number
of health issues for the breed, including high blood pressure, low oxygenation, heart
problems, and difficulty breathing. 4. The Boxer: Part of the boxer’s aesthetic
appeal is their shorter faces, which breeders have continually tried to manipulate to make
even more emphasized. Unfortunately, shorter faces tend to result
in more health problems. Boxers of today have shorter and more upturned
noses, which makes them more prone to breathing problems. Their short snouts also result in difficulty
controlling their body temperature in the heat. 5. The Dachshund: While Dachshunds have always
had small legs, they used to be proportionate to their bodies. The dachshund’s features have been exaggerated
and manipulated through intensive breeding. Now, dachshunds have notably longer backs
and necks, which have resulted in the legs shrinking to the point that their chests are
almost touching the ground. The dachshund is at more at risk to suffer
from intervertebral disc disease (IVDD) than any other dog breed. 6. The White Terrier: In 1915, this breed was
known for its athleticism, great instincts, and overall high functionality. However, improper breeding has tarnished most
of these initial qualities. The breed has been intentionally stunted over
time to make them smaller. This has made them significantly less athletic
and has diminished the breed’s ability to follow their instincts. 7. The St. Bernard: Back in 1915, St. Bernard
dogs were known to be noble working canines, but unfortunately, intensive breeding has
squandered that ability. Now, St. Bernard dogs are over-sized compared
to their ancestors, have shorter muzzles, and have been bred to have abundant skin. A number of diseases have come with these
changes and their ability to work has diminished due to how fast they can now overheat. 8. The Basset Hound: There have been a number
of notable physical changes to this breed since 1915. Improper breeding has caused even shorter
legs, longer ears, and droopy eyes. Now, Basset Hound bodies have gotten lower,
which has resulted in vertebra problems. They also have excessive skin and their droopy
eyes make them prone to entropion, a condition where the eyelid is turned inward, and ectropion,
in which the eyelid is turned outward. Well, that concludes our quick study on the
dogs that humans have forced to evolve. But are there any other cases of forced evolution
we can study today? Maybe some animals outside of the canine kingdom? Yes, in fact, there are some and yes, we are
going to take a look at them. 1) Tuskless Elephants. This is definitely a sad case of forced evolution
put onto animals, and it has everything to do with humans. Let’s examine elephants and their tusks for
a moment. Yes, these gentle giants are some of the biggest
creatures on earth, however, their size does little against a poacher with a gun. This is unfortunate because poachers just
love getting their greedy hands on the elephant’s tusks, and will kill the majestic beast for
their ivory. This is why some elephants have started to
be born without their natural defense mechanisms. LIST VERSE.COM reports that: “In 1969, only
around 10.5 percent of all Zambian elephants were born with a mutation that prevented the
growth of tusks. By 1989, a peak time in ivory poaching in
Zambia, that number rose to 38.2 percent.” If we had to look at the bright side, we’d
say at least the elephants won’t be poached as often. 2) Atlantic Cod. Let’s shift focus from ivory poachers to fisherman
for a second. We want to go on record and say that if you
do catch and release, that’s alright. Also, if you fish legally and only keep the
limit, then that’s alright too. The problem we have is with overfishing, and
that’s the Atlantic Cod’s problem too. Another issue this fish has is that they’re
too delicious, so we humans just love to take them from the water and slap em on a dinner
plate. So much so that the Atlantic Cod was one of
the most overfished water creatures in the world until a moratorium went into place to
protect the species from extinction. However, the Atlantic Cod also took measures
to protect its own kind from going extinct. The Cod apparently knew that when they got
too big, humans would come and pluck them from their blue, liquidy home. So, they started mating earlier, so that they
have babies when they’re smaller. If they’re smaller, then humans will throw
them back and they can keep having babies. Until they get too big, that is. Then they’ve gotta dodge fishermen. 3) Bedbugs. Ew! We went from beautiful elephants to a fish
that only certain people would find cute to something EVERYONE hates. Well, turns out bedbugs know we want them
dead and have evolved to combat our ways. NATIONAL GEOGRAPHIC tells us that “Bedbugs
have evolved to become more resistant to the pesticides we have created to deal with them. They have increased the thickness of their
exoskeletons and have mutated other natural defenses in response to the poisons we use.” So not only can they feed off of us while
we sleep, they’ll even survive when we try to poison them. Just burn the mattress… until they become
fire resistant. Then it’s off to hide in the underground caves! Who’s with us? 4) Mice. We feel that some people are torn on mice. We here at Bestie like mice, because our writers
are rat people. They’re just so adorable when they nibble
on cheese and they have the little twitchy noses… oh, we were talking about our writers,
but mice do that too. Nevertheless, the rodents (and also possibly
the writers) are pests and often carry some diseases. So, occasionally if there’s an infestation,
we’ll need to use a poison called warfarin to get rid of them. However, after experiencing this kind of death
for years, the mice have begun to create a new hybrid mouse that is resistant to the
poison. A German mouse and an Algerian mouse have
combined their genes to create a kind of super mouse, that cannot be killed by warfarin. So, if you find these hairy, black eyed creatures
skittering around in your ceilings, it’s best to call an exterminator. Again, we’re not sure if we’re talking about
mice or our writers. And that’s it! What did you think of our list of forced evolutions? Did you think it was sad? Are you impressed by the ways nature or humans
have forced these animals to change? Let us know in the comments section below
