Why do certain species of plants and animals sometimes become extinct? According to the theory of evolution, individuals of the same species show a range of variations. Some individuals have characteristics that are better suited to their environment, making them more likely to survive and reproduce, whilst others are less well adapted. These less well adapted individuals may eventually fail to reproduce and eventually their genes are removed from the population. If an entire species fails to adapt to changes in its environment, or compete with other organisms for resources, and its birth rate is lower than its death rate, then it will become extinct.
