A new study that was conducted by B.C researchers are saying that bird species, such as the geese are evolving and changing at a fast pace, especially in North America. Birds in North and South America, evolution rate tends to increase. As a result from the fast rate of evolution, the diversity of birds is also increasing. According to studies, due to the fact of all the harmful human activities it will affect these new bird species over a period of time. However, some scientists found out that these new species are developing quickly and as a result establishing many variations for there advantage to survive against these human activities. Biologist Arne Mooers explains, "Birds are special, as they are good at getting around. They can escape from community conflict from other relatives and start a new population elsewhere. As they can produce bursts of new species at different times and in different parts of the globe." To conclude, there are more and more new bird species being introduced into a new bird population. Astonishingly, in the Western Hemisphere is where the bird evolution is happening rapidly more than the Eastern. Many scientists are convinced that climate change may have played a crucial role in this occurrence. 

 

As a student studying evolution, this article gives important information to students and interesting facts about evolution in species. The article talks about what is happening in the ecosystem of the bird population. The article is also saying that humans may have been a huge factor to why this actually happened. As this is important news for many scientists and researchers because it helps scientists understand evolution more and how human's contribute to change evolution, affecting species. This article raises many questions and concerns about how human negative impacts have affected the world by changing environments for species so they can adapt and evolve into better living species. This article is significant because it shows how birds are always experiencing evolution at a rapid rate. As a result, it brings more new species to live in the ecosystem. Since the evolution rate is increasing so is the diversity of birds as well. In the following article some scientists found out that these new species are finding ways to develop many different variations in order to survive. Thus, this relates to Darwin's theory of natural selection because possibly these new species have many different traits, so they can survive against negative human activities affecting there ecosystem. Even though the article did say that how these new species will die over a period of time, other scientists are convinced that this might be a new population of birds to survive. Even Biologist Mooers said that how there producing at a rapid rate. This is possibly because of gene flow because these new bird species were perhaps from South america and migrated up to the North because of their following traits the birds have. Maybe they can't adapt to the South American environment and decided to migrate up to the north because these environmental conditions are better for them, so they can survive longer and produce more offsprings in the north. Mutation could've also caused new bird species because human activities could have led to this source of variation which leads to changes in the bird traits. As a result new bird species are being introduced into a population of birds. To conclude, birds will always continue to evolve because human's are always doing things to affect the earth and other species as well.
