8+Organism+fitness

A. An organism's fitness is determined by "it's ability to survive and reproduce" in it's environment. If the organism has successful reproduction rates and strong offspring, then the species is likely to continue its survival. It is also defined as an organim's competition with other species around it. Depending on the species fitness depends on how long that particular species will last.

B. There are many explanations to describe how fit an organism is. An organism is fit through it's own genetics. The environment that the organism lives in effects the organisms fitness. An organism can't predict where it stands in natural selection, but the more fit the organism is, the better off it will survive. If an organism or species is unable to adapt to its surrondings and enviroment that particular organism or species will eventually become extinct. If an organism or species is able to adapt it will go through changes so it can survive the environment and surrondings.

C. Below is an example of an organism's fitness. Image (a) represents a healthy elephant whose species is still present today. Image (b) represents a woolly mammoth whose species is not present today. The mammoth's species did not survive to present day because it was unfit for the times to come. Just because an organism is healthy, doesn't mean that it's fit too. To be fit, the organism must have a steady offspring and the characteristics to survive in its changing environment. (a) (b) D. There is a possibility that the views on an organism's fitness could change in the future due to advancing __technology__. But more than likely, the view that an organism's fitness depends on "it's ability to survive and reproduce" will stay the same. An organism could also be changed by genetic engineering. Scientists in the future may be able to modify an organism's genes to make it adapt easier. If they are able to modify the genes, it could also be more difficult to have a defined line of which organism is more fit than the other organisms.
