this chapter was weird. i never knew that before fish that only singled cell organisms lived on the planet. also, that is was weird that those cells did not have bodys. i thought that all cells have bodys?
I find it really interesting how our skin cells are constantly dividing. Its cool how we are still the same person we were when we were born but we have a different layer of skin since then.
this is a pretty good chapter in my opinion, because i was able to think. this chapter poses the statement "we remain the same individuals despite the constant turnover of our parts", and made me think well whyare we the same individuals if we grow and our cells are replaced, and i thought of something that i'll bring up in class when we discuss this chapter, regarding human conciousness and awareness.

I really liked the experiments that Shubin describes in this chapter. It was interesting how the organs "know" their place in the body. When I think about it though, it makes sense. If the body couldn't sense everything, not only individually (such as organs) but as a whole, the entire body would just be a jumbled mess. I knew that there were little "messenger" cells in the body, but Shubin made me really understand how they work.
You learn early on that within us are millions and millions of cells, and now you see the importance of cells in forming the body. Although rocks tell us that 600 million years ago there were no plants or animals but single celled creatures. You learn that as time passed our bodies altered as a defense from predators. For instance, the development of bones. As well as how they work and what they are comprised of. I mean I never thought about how even collagen plays such a role in our bones. It's quite an amazing thing. -Loremae Mopera

ReplyDeleteI never knew that those cells didn't have a body until I read this chapter.
