The "struggle to survive", "survival of the fittest" and "natural selection" are all phrases to indicate the main guiding mechanism of evolution: differential reproductive success.
Most believe that the struggle to survive and adaptation causes evolution. If all of the sudden all food was in trees, humans would probably adapt and become skilled climbers, or grow a body part that helps climbing.
Evolution says that survival of the fittest. Illnesses would not be treated because those strong enough to fight them would survive while the weak would die out.
Speciation adds to biodiversity. Hence it affect the evolution of best suited forms to come up.
They struggle to survive and ultimately vanish
The "struggle to survive", "survival of the fittest" and "natural selection" are all phrases to indicate the main guiding mechanism of evolution: differential reproductive success.
This is the fundamental premise of the Theory of Evolution by Natural Selection; the environment has a fundamental impact on the adaptations and evolution of organisms. The environment "selects" for those specimens that survive to have more offspring. Those animals that cannot survive are selected against.
living things over produce variation among offspring struggle to survive desirable traits are more fit.
living things over produce variation among offspring struggle to survive desirable traits are more fit.
To pit it in a more accurate form; the theory of evolution by natural selection. Not a belief, a theory in the scientific sense.

what affect tectonics have on evolution of new spiecies
Individuals suited to the struggle for existence will survive and reproduce better than individuals not so suited. Differential reproductive success is just another name for evolution by natural selection.
Evolution says that survival of the fittest. Illnesses would not be treated because those strong enough to fight them would survive while the weak would die out.
To Build a Fire= By jack London comes to mind. It doesn"t light up!
The term coevolution (affect) is used to describe cases where two (or more) species reciprocally affect each other's evolution. So for example, an evolutionary change in the morphology of a plant, might affect the morphology of an herbivore that eats the plant, which in turn might affect the evolution of the plant, which might affect the evolution of the herbivore and so on.
