6 species of animals that have been fully modified by humans

The evolution of species is simply extraordinary. Several centuries and millennia of practices, improvements and genetic mutations cause species to become totally different over the years.

However, not all evolutionary characteristics occur naturally. The influence of humans on other species is also responsible for several mutations in other animals.

In this list, you will check 6 animals that have gone through this type of “artificial” mutation.

1. Budapest Short-Faced Tumbler

This type of pigeon, which does not have a name translated into Portuguese, is a descendant of the rock pigeons ( Columbia livia), but has several characteristics that distance it from its ancestors. The influence of humans on these animals caused them to develop an extremely small beak, almost non-existent, and a totally different appearance from their peers.

2. Gibber Canary Italic

This type of canary did not arise naturally, but because of creations systematically organized by human beings. Breeders strive to reach these genetic mutations in order to create breeds with pleasant songs, different colors and unique appearances.The problem, however, is that this is not entirely healthy for animals. The vast majority of bird species that undergo evolutionary mutations caused in laboratories and human creations face various health problems during their lives. Birds suffer from uncontrolled growth of feathers, inflammation, infections, among other problems.


3. Chickens without feathers.

This is perhaps one of the biggest “freaks” humans have ever done to birds. Several years of breeding and laboratory testing have enabled scientists to change the DNA of chickens so that their embryos do not develop feathers during formation. Because of this, birds are born completely “naked”.

It goes without saying that this is immeasurably harmful to animals

4. Rhodesian Lion.

This is just one of the dog breeds that have been affected by humans. The Rhodesian Lion was “bred” especially to help people during hunts, but the genetic mutation to which it was subjected ended up leaving it with a great vulnerability to diseases.

Due to an abnormal growth of hair on their back, most dogs of this breed develop dermoid cysts, which are small holes in the skin. These holes can be very deep, and often leave extremely delicate nerves and tissue exposed – which in turn is a smorgasbord for bacteria, fungi, viruses, and so on.

5. Bubble eyes

This type of fish has long been used as an ornament in aquariums. Bubble Eye (or Bubble Eye) suffer from serious health problems due to deformities in their eyes, which many even burst.

6. Damascus Goat
