I like to learn~
Yesterday I got a letter, a tape and some candy from my friend J____ who is in the MTC. I felt a little bad, I should have been the one sending her the letter, tape, and candy. Oh well. The tape was awesome. It reminded me of how much we grow. Every time we leave our comfort zone and stretch ourselves we make amazing progress. So there's my first part of the blog.

Here's the second: have you ever wondered what marsupials are? And what about all those other wierd things, the monotremes? How are they different from "normal" (placental) mammals? I will tell you.

First of all, marsupials and monotremes are mammals. Mammals have mammary glands, which produce milk (learn about mammals in one of my favorie songs). If you are reading this you are a mammal. There are several types of mammals that have split apart as evolution has occured. The first branch that split from the mainstream mammal tree is the monotremes. Monotremes are perhaps the weirdest mammals around. The order Monotremata only has two members: the platypus and the echidna. Monotremes lay eggs!!! They also don't really have nipples, they just excrete milk from their skin. Talk about neat! Oh yeah, and the male platypus has a venomous spine on its ankle. The echidna has a spine, too, but it's not dangerous. I think that's enough for one day...we'll move on to marsupials later, and then maybe touch on placental mammals.

    Awesome post. Have you ever seen a Monotreme in person?

    Next, why don't you do a review of exothermic plants?

  2. Maybe I will...someday. Actually, it sounds like a good idea. I think you know more about it, though.

    To my great sadness, no. I have not seen a monotreme in person, only in my mind (and in pictures and on TV)

  3. A placenta is just a very flimsy egg. We're not that different from the monotremes. :)
