Key Theories and Concepts in Evolutionary Biology
Foundational Theories of Species Change
Fixism: Species Stability Theory
Fixism is the theory that species were created following a predetermined pattern and, therefore, have always remained the same.
Key proponents include Georges Cuvier and Carl Linnaeus.
Evolutionism: Species Transformation
Evolutionism defends the idea that species have changed and transformed over time.
Key proponents include Jean-Baptiste Lamarck, Charles Darwin, and Alfred Wallace.

Public Finance Fundamentals and Market Failure Correction
Public Finance Fundamentals
Meaning of Public Finance
Public finance is concerned with how governments raise money, how that money is utilized (spent), and the effects of these activities on the economy and society.
Definition by Hugh Dalton
“Public finance is concerned with the income and expenditure of public authorities and with the adjustment of one with the other.”
Scope of Public Finance
The scope of public finance traditionally covers several key areas:

Essential Marketing and Pricing Frameworks
Price Elasticity of Demand (PED)
Formula:
Price Elasticity of Demand = % Change in Quantity Demanded / % Change in Price
- Elastic (> 1): Consumers are sensitive to price changes.
- Inelastic (< 1): Consumers are less responsive to price changes.
Strategies to Make Demand Inelastic
- Differentiating the product.
- Building strong brand loyalty.
Elasticity and Product Types
- Luxury Goods: High elasticity (flatter demand curve).
- Normal Goods: Lower elasticity (steeper demand curve).
- Perfectly Elastic Goods: Horizontal

- Receiver (Listener): The person the message is intended
Software Engineering Fundamentals: Estimation, Design, Risk, and Quality Assurance
Software Project Estimation and Decomposition
Decomposition Techniques in Estimation
Software project estimation is similar to problem solving. When the problem to be solved is too complex in software engineering, we decompose the given problem into a set of smaller problems.
The decomposition can be done using two approaches:
- Decomposition of the problem (e.g., breaking down features).
- Decomposition of the process (e.g., breaking down tasks).
Estimation uses one or both forms of decomposition (partitioning)

- Point: Exact location in space with no size, written as a capital letter (e.g., A).
- Line: Straight path extending infinitely in both directions, no thickness, named with two points ($\overleftrightarrow{AB}$) or a lowercase script letter.
- Plane: Flat surface extending infinitely in all directions, named with a script capital letter or three non-collinear points.
- Collinear Points: Points that lie on the same line.
- Coplanar Points: Points that lie
