Yes, they know they need to change to survive

No, they change because of natural selection
|
Detailed explanation-1: -Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
Detailed explanation-2: -Individual organisms don’t evolve. Populations evolve. Because individuals in a population vary, some in the population are better able to survive and reproduce given a particular set of environmental conditions.
Detailed explanation-3: -There have been described several ways of evolution which do not require natural selection, the most well-known among them being the random walk, i.e. neutral evolution. However, these cannot create adaptations.
Detailed explanation-4: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
