Matching skip

Short Answer skip

2. when humans modify other species by selecting and breeding individuals that possess desired traits
   
3. the study of the anatomy of various animals
   
4. hybrid offspring of two different species reach maturity and are vigorous, but sterile
   
5. a few individuals colonize an isolated island or other new habitat
