The difference between the two is that strong artificial selection is applied during both prezygotic (before conception) and postzygotic (after birth) points in the animal’s life‚ the weak form only deals with postzygotic selection. The weak form can appear to be simply taming‚ and therefore has less of an impact. Even though the effects of it are still seen today‚ artificial selection of these animals was practiced long ago.

Analyse the human impacts affecting the nature and rate of change of two ecosystems at risk. All ecosystems are placed under levels of stress that must be withstood or overcome in the form of evolution in order to adapt and survive. These attributes determine the resilience and vulnerability of each and every ecosystem. These forms of stress fall under two categories; natural and human induced. In regards to natural stress‚ the term gradual is used as it happens at a slower rate and lesser magnitude
