1. Alfred russel wallace travelled to amazonia in 1848.wallace noticed many plants and animals had special features enabling them survive the conditions which they lived .these observations led wallance to develop a theory about how species of animals and plants gradually change through a process known as natural selection
2. natural selection is the process by which species adapt to their environment
3. Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring.
4.It is the one process that is responsible for the evolution of adaptations of organisms to their environment
5. so it is one of the great contribution by alfred russel as it is the one process that is responsible for the evolution of adaptations of organisms to their environment.
