There are two major clades that diverged from one another over 55 millions years ago: one that includes Canids and its relatives and one that includes Felids and their relatives. By just observing the clade that includes Canids,
what does it tell you about Canid evolution specifically compared to that of its relatives?

i dont know it at allnow im just getting points at this pint

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
