Trying to tie Computer Security into all of this

Using Darwin’s approach

Really slow: it took biology billions of years to get to the efficiency it now is at. How are we supposed to compete with that?
If we follow the same process we are setting up for failure most of the time…species getting extinct because they failed most of the time
Species survival is highly dependent on environment…computer security needs to basically work all the time independent of its environment …how is this going to work?

So for things to work:

there needs be a lot of redundant stuff:
- Genes – redundant ways to get an amino acid
- Genome – copies of the same genes
- Pathways – many regulators
diversity
- Biology is so good because there aren’t two things that are really the same…they have a lot in common…but there is that one small aspect that sets them apart…if they were all the same then one small thing just wipes all of them out
- Can this be done with computers…randomize things by adding introns (junk code)?

Textbook Notes

Chapter 1: Light and Life==

Electrons become excited when absorbed by light which in turn then becomes potential energy (photosynthesis)
Photoreceptor

Circadian rhythms (body clock) the daily cycle of most living organisms have evolved to adapt to the change in light (night and day…plant use photosynthesis during the day and night break glucose)
Some animals prefer the dark (nocturnal animals like moths)
Some animals have ancestors that had functional eyes but are not blind (blind mole rat)
bioluminescent: organisms that use chemical energy to make their own light to attract a mate, camouflage, attract prey or communicate

Display order: high ordered structures
Harness and utilize energy: getting and using chemical energy to power the organism’s activities
Reproduce: ability to reproduce their own kind
Respond to stimuli: ability to respond environmental stimuli
Exhibit homeostasis: ability to control an organism’s internal environment within the limits to sustain life
Growth and development: consistent growth and development (DNA inheritance)
Evolve: adapt to environments over many generations to have better reproducibility and survival of the species.

Function	Organelles/Structures involved
Genetic control of the cell	Nucleus and ribosomes
Manufacture, distribution, and breakdown of molecules.	Endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vacuoles, and peroxisomes
Energy processing	Mitochondria (plus chloroplasts in plant cells)
Structural support, movement, and communication between cells	Structural support, movement, and communication between cells

Mitochondria and chloroplasts evolved by endosymbiosis which suggests mitochondria and chloroplasts were small prokaryotes and they began living within larger cells
Cytoskeleton:
- network of protein fibers in the cells
- functions in structural support and mobility
- interacts with motor proteins resulting in mobility and cellular respiration
- composed of three kinds of fibers:

Microfilaments: (actin filaments) support the cell’s shape and are involved in mobility
Intermediated filaments: (not present in plant cells) reinforces the cell shape and provides and anchor for the organelles
Microtubules: (made from tubulin) responsible for cell rigidity and guiding the organelle’s movement
