1. Homologues
a.
Human Tail Bone and Monkey Tail; The homologues
trait they both possess is that they both have tail bone.
b.
The Homologues of Human Tail Bone and Monkey
Tail. The Human Tailbone and Monkey tail have similarity trait but as evolution
have gone human vestigiality of it structure express the lost function as to
where monkey can use it to grab hold on to something and move it tail around.
c.
Human share common ancestor with African Apes;
Monkey ancestor with Primate. Although they are very practically almost the
same species monkeys are much smaller than apes and humans.
d.
2. Analogous
a.
Human and Snakes; The analogous trait both
possess is they both have femur but use for different thing
b.
The Analogous trait between human and snake is
that human is mammals and snake is a reptiles. But they both still have femur.
For human is use for walking and jumping but as for snake it is useless and
just floats.
c.
Yes, it is possible that the common ancestor did
process analogous trait. Possibly that snake could walk before but change over
time to fit the environment.

Paul,
ReplyDeleteIt was interesting reading your post, but it might be better if you made the points into a paragraph with proper transitions. Going more into depth with the traits can help too. For example, you could have researched about snakes and given facts that they could walk before rather than assuming. Other than conducting more research and making your points into paragraph form, you did a well job in this blogpost. Good job.
Good identification of this homologous trait. When you talk about monkeys using their tails for grasping branches, are you talking about all monkeys or only certain ones? Also, when discussion ancestry, understand that all of the organisms you listed are primates. Every one of them, humans, non-human apes and monkeys (and prosimians). So it is more direct to state that the ancestral tail trait was inherited from the primate common ancestor.
ReplyDeleteThe femur in humans and snakes ARE homologous traits, not analogous. Both arose from tetrapod ancestors (amphibians and then reptiles) who shared the ancestral limb structure. Snakes lost most of the limb but retained the femur (it is used in reproduction). Same ancestral femur but different function/structure = homolog.
