Convergent+Evolution+and+Coevolution

Convergent Evolution:
Definition: Unlike divergent evolution, convergent has nothing to do with species being related. However, it deals with different species that have similar characteristics. These characteristics are not based on what they evolved from but by the similar habitats that the very different species live in. Because they adapt to these environments, they tend to have similar characteristics.

Example: Yaks and llamas cannot be traced back to one type of species. They don’t contain the same ancestors. However, the one thing they do share in common is their act of survival in the environments in which they live. Both animals live in high altitudes in mountainous areas. In order to stand the extremes of the air pressure and temperature, these animals have adapted similar characteristics such as heavier coats. Darwin: Another example that is commonly brought back to Darwin, is bats and birds. They also aren’t traced to the same species, but due to environments they’ve migrated and adapted to, they were able to grow similar structures that allow them to fly.



Coevolution:
Definition: Coevolution takes place as one type of species affects another type causing evolution to take place in both set areas. In a population where there is multiple species, coevolution consistently takes place as other species are changing. It appears to become a domino effect where one effects another and it continues on.

Example: Humans are a prime example of this. We often selfishly benefit ourselves, while changing other species. By building and extending our buildings to provide more housing, we ruin the environments of many different species. For example, the giant panda bears, usually found in Asia, are becoming more and more endangered. This is largely due to the immense population China actually has. Losing that species then affects many other species, because there is more bamboo for other species and less pandas in surrounding areas.
