Natural
selection allows you to create new species, improve living longer and provide
competent development of the biosphere as a whole. Its advantages in a
measured, maintaining the diversity, the presence of species that can survive
in the event of a major disaster. But with all the conservatism and systematic
development, there can be seen a huge minus. Namely, the number of individuals
who have died just for the fact that to pass genetic material.
Evolution
today is so slow, almost imperceptible to an outside observer. Natural
processes are too slow for what would have to talk about positive changes
within a species. We unnoticed by the way changed the DNA line than one
generation of animals is different, and changes in their own bodies, often
escape our attention.
And when
natural processes actually frozen, people started customizing them
artificially. We do not act blindly. We competently construct the structure of
the new plant, carefully monitor the growth of crops, selection and correct
order of gene transfer into the new structure. The genesis of all life does not
stop. He stopped that man would give it shape, cleared of defects and ran on.
And where it leads, it depends only on us.
