THE ENDOCRINE AND NERVOUS SYSTEMS IN LIVING BEINGS.
Storyboard Szöveg
- Well I think you look weird, with that large beak! Also these canyons are very comfortable to live in. I like it a lot.
- What a weird beak you have! Also that place looks dangerous to live.
- Whatever it is, it looks dangerous. I should protect myself!
- Let's huddle together to get warm!
- Not only do the different species of animals from different environments look different, they have different nervous systems that are going through evolution processes.
- I feel a sandstorm coming! I should prepare!
- I hear something...!
- Primitive systems serving newer functions
- The two aspects of the evolution of animal nervous system are:
- Now I can see better in the dark with my adaptive optic lobe!
- With my new echolocation system, now I can sense things better in the dark!
- Formations of new systems serving newer functional requirements.

- The long evolution of the human's nervous system
- Over time, humans' nervous systems have went through evolution based on the environments, and are yet non-stopping. As mammals, humans have a highly developed nervous system with a high degree of cephalization and developed cerebrums and cerebellums.
- we should start changing soon...
- Yeah, at least in 100 years or so.
- Same here. Now that the environments changed a lot.
- I knew I should mention this someday but we ARE actually in the process right now.
- I think I'm smart.
- Oh then. I guess I'm the smartest.
- Then how would the nervous system evolution systems look like for other vertebrates? For the brain of vertebrates, there is a general trend with the increasing size and complexity of the cerebrum and cerebullum from fish, amphibians and reptiles, and to bird and mammals.
- I'm smarter though.
- ...hah!
- Me too.
- For me, I have a centralized nervous system with a small ganglia..but you know, this helps me a lot.
- Invertebrate nervous systems involves of nerve nets, nerve cords, and ganglia.
- Flatworms
- I have nerve nets that help me be successful as a predator.
- Cnidarians
- Gabin Kim
- Cephalopods
- Athropods and I have a brain, and specialized sensory organs.
