Charles Darwin Domestication Essay
One day in 1855, Charles Darwin went for a walk in London. He saw some pigeons and wondered if they had a common ancestor as fancier pigeons. He observed them and concluded that both species descended from the rock dove. He believed that since man could breed several forms from a single thing, nature could too. Domestication became a laboratory for Darwin to study evolution. Charles Darwin noticed that in mammals, virtually all domesticated species shared some characteristics that their ancestors didn’t have. Darwin thought these characteristics would have something to do with the hybridism of different breeds or the living conditions of tamer animals, but he couldn’t explain how such a process could produce such a broad spectrum of features

The areas that are smaller are the parts that give an advantages to wild animals, such as the part that enhances sight, hearing, or smell. The process of domestication is hard to reverse. Dingos have been wild for over 3000 years, but they still have the small brains that their domesticated ancestors had. Domestication of animals has not only changed the way many species live today, but it has also changed the way humans live. It used to be that humans couldn’t digest lactose. They gained the ability once they started to domesticate animals that produced milk. This is because they started to get a steady supply of it and their bodies adapted to digesting a certain enzyme in milk. Humans could drink milk before that, but research shows that it was probably uncomfortable. With the introduction of domesticated farm animals, and with that came agriculture. Agriculture exposed humans to a plethora of different pathogens. Clearing land for crops created standing pools of water, which became breeding grounds for the deadly diseases that mosquitoes carried. Blood irregularities found in humans are thought to have been a result of
