Instinct+Genetics



.
 * Driving Question: **

How do animals instincts compare between species from the land, sea, and the air, and how to they effect the evolution of the organisms?

Describe your Topic below:

For our group project, each group member has picked a different species to research. Justin has a marine animal, Pat has a land mammal, and Ashley has a bird. We all intend to look into the individual instincts of our specific animal, as well as it's evolution, and when we conclude our individual research, we plan to compare the instincts/evolution of the animals, and find what the genetic basis is for these evolutionary and instinctual characteristics.

Brainstorm what you know and what you would like to know:

An example would be how baby sea turtles are born on the beach, automatically go to the water. -We know that evolution plays a part in which animals (the stronger, fitter, and better adapted) survive.
 * = ** What we (think) we know ** ||=  ||= What we would like to know / understand ||
 * -We (think) that animals are born with their instincts, that they are inclined to a specific behavior without ever being taught.

||  || -We want to understand how instincts are "triggered" What is it that tells a sea turtle to go to the water? Why are they inclined to do certain things and why in some cases do they go against the "norm" of their species? -We want to know if instincts play a role in evolution. Do some instincts cause an animal to be less adaptable and therefore cause it to die out?

This video describes negative and positive feedback loops. These are important to evolution because they regulate everything the body does, including create amino acids, proteins, and genes. This is crucial in evolution, and in the creation of genes.

FEEDBACK: __Signaling, Sensing, and Reacting__

Organized Cells: -keep things moving -don’t allow pile up of products -flexible and prepared to respond -oversee production -repair and replace

FEEDBACK LOOPS:
 * input of raw materials to output of products

NEGATIVE FEEDBACK LOOP:
 * information flows in a circle, controlling the rate of assembly
 * first enzyme controls the build up of amino acids
 * stops the assembly line and waits for amino acids to be used
 * begins assembly again when amino acid count is low

*negative feedback loops end in the opposite of what you began with. *accumulation of the end product of a process slows the process

POSITIVE FEEDBACK:
 * end product speeds up production
 * product stimulates an enzyme in a sequence, which increases the rate of production of the product
 * less common

Our Animals:

Ashley- Mockingbird Pat- Tiger Justin- Tigerfish

Each picture links to a facts website on each animal that we will be using as a basis for our projects.
