Adaptations inherited characteristics that came into existence through natural selectionb/c they aided in solving problems related to survival or reproduction (umbilical cord) By-products: characteristics that do not solve adaptive problems but are coupled to adaptations (belly button) The time and place evolution occurs to deal with a problem faced by a species. Problem of surviving surviving long enough to reproduce. Mating getting and keeping a bae long enough to pop one out. Parenting helping your kids live long enough to do the same thing problems of group living tasks relevant to helping out fam that aren"t your kids.
