In the context of Earth's living history, rapid urbanization is a relatively recent phenomenon, yet biologists have already observed evolutionary change in numerous species compared to their rural counterparts on a relatively short timescale. [1] [2] Strong selection pressures due to urbanization play a big role in this process.
Urban ecology is a relatively new field. Because of this, the research that has been done in this field has yet to become extensive. While there is still plenty of time for growth in the research of this field, there are some key issues and biases within the current research that still need to be addressed.

Research on European blackbirds (Turdus merula) has shown that there is a significant variation of songs of the European blackbird along a rural-urban gradient. This is probably to avoid the song from being masked by the background noises.
