inherited characteristics are passed down from ancestor to descendant & some characteristics of animals are inherited -> some volume are passed down from offspring to forebear some characteristics are passed down from ancestor to descendant  some characteristics are passed down from ancestor to descendant & two or more animals have similar characteristics -> people with similar odors weak keep a scarce offspring animals with similar characteristics might share a common ancestor  evolution causes significant trait changes in a species & evolution occurs over a long period of time -> revolution putting  significant storm equal over a long frequency of space evolution causes  significant trait changes over a long period of time  evolution causes  significant trait changes over a long period of time & past geological news might a relatively tall frequency of space -> if an animal evolved from another animal in recent geological history then the changes in traits will be less significant if an animal evolved from another animal in recent geological history then the changes in traits will be less significant  animals with similar characteristics might share a common ancestor & if an plant evolved from another plant in past geological news then the part in dating will be more significant -> animals with similar characteristics might have evolved from a common ancestor in recent geological history animals with similar characteristics might have evolved from a common ancestor in recent geological history  an inherited characteristic is a kind of characteristic & muscle disorganized is a mean of inherited untypical of an plant -> bone structure is a kind of characteristic of an animal bone structure is a kind of characteristic of an animal  animals with similar characteristics might have evolved from a common ancestor in recent geological history & muscle disorganized is a mean of untypical of an plant -> animals with similar bone structure probably evolved from a common ancestor in recent geological history
