Chapter ##: 0  - Term ​ - How the earth started/development (motivation)  - Term ​ - Darwin ( adaptation and natural selection)   - More explanation  - Earth (13.1 billion years old)   - Australia was the location where we found the first organism   - Archean Stromatolites   - Chemical floating around in that water,   - Protein than RNA leads to cell membrane, to a nucleus.   - 2.5 bya  something recognizable as life  - Descent with modification.   - More explanation  - Life tends to increase exponentially (page 3 of textbook) there is a graph  of that.    - Darwin equation N=X^tXN.  -  N1=2xN the population will double   - Example: One kid per couple in China.   - As lambda increases, population will increase.   - Darwin was talking about genetic contribution to fitness  - Term-  ​ Malthusian growth curve   - More explanation   - Log(N1)= t[log(X)] + log(N)  - All the curves for lamda will become straight lines.   -

The ability for humans to manipulate

(Symbiosis relationship)  - Medicine ​→ human medicine from our understanding of both  normal and deviant behaviors to the understandings of our  evolutionary history. (sickle cell disease, have the edge)  - Natural product​ → Even our discovery and development of useful  natural products is enhanced by evolutionary taxonomy. Useful  chemical camphor obtained from Eucalyptus, and we want to find a  more suitable minor chemical variations. You need to understand  evolutionary taxonomy.    - Conservation biology​  → We are losing thousands of species every  year. We are subjecting them to environmental insults that are  simply too large for them to handle. They cannot evolve fast  enough, to intervene we need to understand evolution.   - Understanding ourselves​ → Anthropology is all about making  sense of us in evolutionary terms   - Term-​ Essences   - More explanation   - Philosophical issues  - Before darwin there was the idea that each species had its own  essence that represented what it was all about.   - Term-​ purpose   - More explanation   - It is a driven process   - We need to stop thinking about adaptations as having a purpose.  - Rather those who had gene found an ecological niche that could be  exploited.   - Term​- Evolutionary Theory And Hypothesis   - More explanation
