原文：So the professor discussed about how human activity affects animal evolutions. The professor discussed how human activity affects animal evolution.（删除了多余的“about”，将“evolutions”改为单数形式“evolution”。）

The first changes caused by human activities is that animals tend to have smaller bodies because it's likely to be the food source of humans and to increase the survival rate. The first change caused by human activities is that animals tend to have smaller bodies because they are less likely to be used as a food source for humans, thus increasing their survival rate.（将“changes”改为单数形式“change”，将“is”改为“is”，调整了句子结构以使其更自然。）

For example, some fish, because people only catch larger fish for food, and some species mate with smaller fish and reproduce, so that some species are much smaller than before. For example, in some fish species, people tend to catch larger fish for food, leaving the smaller ones to mate and reproduce, resulting in these species becoming smaller over time.（调整了句子结构以使其更自然。）

And the second effect is that the larger brains animals tend to learn how to live in different habitats. The second effect is that animals with larger brains tend to adapt better to different habitats.（调整了句子结构以使其更自然。）

For example, mice used to live in forests and rural areas, and since human activity changed their habitats, bigger brain mice tend to find food in the city. For example, mice used to live in forests and rural areas, but due to human activity changing their habitats, mice with larger brains are better at finding food in urban environments.（调整了句子结构以使其更自然。）
