your question is very complex: from the beginning of time, more and more species had appeared and disappeared (the second most) and had a major impact on the ecosystems they lived in. In your question, you asked about the effects; well, the effects can be of both types, positive and negative, but mainly if a new specie is put or born in an ecosystem, it will probably adapt, instead of ruining it. Genetics offer a new perspective upon life and i think that if man can create a specie that is stronger and healthier than its original and if that specie can fit perfectly in an ecosystem,that would be a step towards evolution.
