ROAR 5-4-3-2-1 #5

Hey you guys!! ^^ I'm big on midterms and test on going so it might take some time for me to update you guys! Sorry! =[ &Also OB IDOL TOMORROW!! ^^

Here's a quick 5.4.3.2.1 synopsis!(: Take Care!


The New Science Of Evo Devo: Endless Forms Most Beautiful
Sean B. Carroll

5.Comments:
* Back to the switches, here how some genetics switches works: There are activators, and repressors and the act as switches. There is abd activation of effects, multiple of activators and repressors are involved in the building patterns od any structures.
* End of that, back to Cambrian Explosion: the so many Arthropods. Oh then the next few pages are phtographs... real live photos! How great is that? anyhow, there are embryos of flys onces again but now you can actually see the subdivision of it turning into a fly. And all it's body parts. ^^
*The pictures are really cool, it's all neon and glowy.... wow so fantastic! Back to the tool kit genes.. and the embryo is startign to shape itself. Now to the Cambrian arthropods, there are the Marella, Olenoides, Waptia, Yohoia which all have a dominate feature in the similar appendages. Though they do difference themselfs with oth body parts. And continue with the Aysheaia, very different spieces but have some common bodies.
*Next the shitfing zones of the Hox Genes that shap the major different in the arthropod designs. example: an insect, centipede, brine shrimp, mysid, lobster, cleaner shrimp and the trilobite, these have common features but what makes them so different...? Read it and figure it out.
* Next chapter, the evolutionary of inventions, for again examples: paper clips: the Gem (most used) the reeve, wright, and philadephia. These all perform the same tasks but they been inventing new different technology to adapt a better performace... same with organisms and mdern technology.

4.Question:
* How did people start to think about all the advanced technology to actually make them?
*Does that mean the insects, centipede, brine shrimps and so on all came from a common ancestor?
* How were the scientists and biologists able to take all took pictures?
* Was the first real animal the arthropods? If not why are they such a big deal? Was it because their genes were complex?

3.VOcabulary:
*Blastopore: Embryology The opening of the archenteron.
*Cervical: the neck, esp. the back part.
*Schematically: pertaining to or of the nature of a schema, diagram, or scheme; diagrammatic.

2.Literary Terms:
*Imagery: ? The descripton of how the switches works, they presented as a kind of a map ?
*ehh.... none..

1.Overview:
* SO we're starting on the genetic switches to the Cambrian Era agai nto the Arthropods. The complex structures of organism that now are present and the technology of inventions that became for dependable. It relates to living organisms because we as well will evolve and be able to adapt to different situations.
