Cow

Holstein cows, originated in Europe, were bread to make best use of the resources in Europe, for example their grass. These animals were easy to domesticate and were used to the advantage of humans. They were bread for their meat or milk, and also came in handy for labor in farming.

We as humans also put thought in genetically changing these cows for better characteristics. Genetic changes involved either embryo transfer or choosing the best of cows to pass on the next generation. That meant for the owners to select the more healthy cows and let them reproduce, creating more cows with genetic advantages.

If the United States had not had the cows they would not have beef. Then, if they hadn't had the cows, they would be left with pigs and horses. Horses are pretty useful for transportation but pigs don’t do anything at all. The only thing you can do with a pig is eat it.

The cows gave the United States a little push ahead, because cows provided both protein and calcium. This gave them nutrition. It also gave them power for farming so it didn’t have to all be man power.

The cow has limitations on where it can be bred; it can't survive in climates that are too cold or too hot because its hide is not enough to protect them from drastic climate changes. It needs to have grass fields to graze on, so it needs to be living in surrounding where there is constant vegetation growing all year round.

Cows, other than its use for meat and milk, can also be domesticated to pull heavy loads for us. This helps agriculture because the cows can pull loads faster and easier than us. And when we don’t need to worry about doing all the hard work, we can think about other stuff, life forming jobs, finding new ways to do stuff, etc. People have more time to expand and so they do.
