Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
Natural selection is the process whereby a species changes slowly because genetic variations are "selected" by merit of the environment killing off members of the species which do not have them.
For instance take horses. In any group of horses there will be countless variations, most of which don't impact survival or reproduction, but some of those variations might make the horse faster, slower, have stronger/weaker muscles, better or worse endurance etc etc etc, so if say a fast predator migrates into those hoses' environment it will pick off the slower, less strong ones with less endurance etc, and the genes responsible for those traits will become more dominant in the gene pool because those members of the species which have them will survive longer and reproduce more over many generations.
Natural selection might favor sharp teeth, claws, skin which retains moisture better, a stronger immune system or countless other things.
Complex or new mechanisms occur via natural selection as well, usually through a series of intermediaries. Countless mechanisms said to be "unevolvable" because of their complexity have been broken down through a series of useful slight improvements, including such notable examples as the bacteria flagellum and the eye.
As long as the prerequisites for natural selection are met, it will continue to happen. So as long as there are lifeforms that reproduce with variation, and those variations compete against one another for resources and mating opportunities, natural selection is happening.
It doesn't. What is selected for, or how severe the selection pressure is, depends entirely on the physiology of the variant or population, and on circumstances.
It shows natural selection by showing how different birds have adapted over time to continue living, and the birds which didn't adapt, went extinct.
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
The theory of evolution by natural selection.
They adapt and evolve through the process of natural selection and learned behaviours.
the theory about how organisms change over time.

Natural selection
No, but adaptive change would be difficult. Remember, evolution is the change in allele frequency over time in a population of organisms. Mutation, genetic drift, genetic flow and other processes would continue without natural selection.
Yes
The pesticide resistance develops over time due to the natural selection.
inheritable

Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.

The natural change occurring in communities or ecosystems over time is referred to as Evolution.
