Week #4 -Comparative Primate Blog Post
1. Lemurs- 3.1.4.3/3.1.4.3. Different teeth than any other primate in this assignment. They have 3 incisors, 1 canine, 4 premolars, and 3 molars , on both top and bottom. They are from Madagascar, live nocturnally, and are herbivorous.They are smaller in size so they prob tend to need more sharp front teeth for protection and diet.
2.Spider Monkey- 2.1.3.3/2.1.3.3. These have the same as every other primate in this activity except for Lemurs. They have 2 incisors, 1 canine, 3 premolars, and 3 molars. They are from Central and South America, live Diurnally. They are bigger in size. They have bigger bodies and skills, they can protect themselves easier. they hang out in trees away from certain predators.3. Baboon- 2.1.3.3/2.1.3.3. These have the same as every other primate in this activity except for Lemurs. They have 2 incisors, 1 canine, 3 premolars, and 3 molars.They are from Africa, Asia, and Southeast Asia. They are Diurnal, they range in many varied sizes. They are truly omnivores.Live in mixed social groups which cause for giant teeth to scare off predators and capture larger prey.4.Gibbon- 2.1.3.3/2.1.3.3. These have the same as every other primate in this activity except for Lemurs. They have 2 incisors, 1 canine, 3 premolars, and 3 molars.They are from Southeast Asia. They are Diurnal and are around 13 lbs. They eat fruit, leaves, flowers, and insects. Swing from trees, to avoid predators, and capture prey. Large teeth, especially canines, for larger prey. Smaller in size compared to other primates.5.Chimpanzee- 2.1.3.3/2.1.3.3. These have the same as every other primate in this activity except for Lemurs. They have 2 incisors, 1 canine, 3 premolars, and 3 molars.They are from Central Africa. They are diurnal, around 80-100lbs. They are omnivorous. They live in extended communities. They are large and need to capture bigger prey so they have large incisors and big canine. They tend to be more complex mentally, like humans.

I thought it was quite interesting to know that every one of the primates have the same type of teeth except for Lemurs. I thought it was great that you talked about the size of each primate and that fact that Lemurs may need sharper teeth to protect themselves since they are so tiny. Good job!
ReplyDeleteI thought your blog post was intersting, so far you where the only person to choose pictures of the different primates skulls. I found it interesting to learn that chimpanzees are more more complex mentally like humans. I also thought it was interesting that lemurs have different teeth compared to the other primates from this activity.
ReplyDeleteHow many premolars (or bicuspids) do you have? Keep in mind that your dentition (an ape's) is like the same as the chimpanzee, gibbon and baboon (unless you are missing your wisdom teeth).
ReplyDeleteYou have the correct dentition for lemurs (which is highly variable) and for the Spider monkeys (NWM) but check your dentition patterns for OWM and apes (including humans). All have the identical dental patterns, but they aren't the same as NWM.
I would have liked to have seem a lot more discussion on how the dental patterns were adaptations... in other words, how the different dental patterns were related to diet or behavior.
you better check your dental formulas.. they are incorrect.... e.g., chimp is 2123/2123
