So basically its like every animal has all the leading characteristics. for example, you marked that the shark has a vertebra that is correct now you would go onto the Ray-finned fish, you would follow the cladogram lines and x off Vertebra and Bony skeleton you had this correct as well. Now going onto the Amphibians, you would follow the lines again as before and x off everything you've already ticked off plus four limbs because it falls underneath. you would do this for every category and characteristic. Hopefully, this makes sense!! The rest after Amphibians needs to be revised its not correct. :)

<span>What a fascinating question! Just out of college, on my first job,
I was called to the delivery room to assist the obstetrician in
collecting a blood sample from the not-yet born fetus? scalp. I was
nearly immobilized at the sight of the impending birth. Ever since
that night, I have gotten goosebumps when witnessing a birth. It is

conception to birth is marvelous!
Some of the material I have found is published by religious, political
and anti-abotion sites. Neither Google Answers nor I endorse any of
these sites. Such web pages were cited here for conception and
gestation information, and not because of ideology.</span>
