1.1 Scientific theory about human origin
- The scientific theory of human origin is also known as the evolution theory.
- Charles Darwin developed the theory.
- The theory posits that all living organisms change over millions of years, evolving from simple to complex forms.
- This evolution occurs through:
- Mutation: Changes in genes and body behavior.
- Natural Selection: Survival of the fittest organisms after mutation.
- Adaptation: Organisms adjusting to new environments after surviving mutation and natural selection.
Stages of Human Evolution
- Stages include Aegyptopithecus, Dryopithecus, Kenyapithecus, Australopithecus, Homo habilis, Homo erectus, Homo sapiens, and Homo sapiens sapiens.

Types and Uses of Scales on maps
- A scale is the ratio of distance on the map to the actual distance on the ground.
- It helps understand the relationship between map distance and physical world distance.
- Types of scales:
- Statement scale.
- Representative scale.
- Linear scale.
Statement scale
- Written description of the relationship between map distance and ground distance.
- Example: 1 centimeter represents 100 kilometers.
Representative scale
- Ratio scale expressing the relationship between map distance and ground distance.
- Example: 1:10,000, meaning one unit on the map represents 10,000 units on the ground.
- Also referred to as a fraction scale.
Linear scale
- Graphic representation of the relationship between map distance and ground distance.
- Shown as a bar or line with markings indicating distance on the map and ground distance.
Uses of scales on Maps
- Measure distances on maps and compare them to actual ground distances.
- Determine the level of detail a map can display.
- Enable drawing maps expressing actual distances on a small flat surface.
- Determine the shortest route for navigation.
Converting scales
Converting representative fraction scale into statement scale
- Example 1
- Convert 1/200,000 into statement scale.
- Solution
- First convert the denominator which is in centimetres into kilometres.
- (200,000÷100,000=2Km)
- Therefore, the representative fraction when expressed as a statement scale is 1cm on the map represents 2 kilometres on the ground or 1cm is to 2 km.
Converting linear scale into representative fraction
- Example
- R. F. 1:50,000
- Convert the given linear scale into a representative fraction scale.
- Solution
- You start by converting the linear scale into a statement scale by measuring the distance represented by 1 cm on the linear scale.
- 1cm represents 1km.
- Then convert the statement scale into a representative fraction scale.
- 1km = 100,000cm.
- Therefore, 1 cm will represent (1×100,000=100,000cm).
- The representative fraction scale (RF) is 1/100,000 or 1:100,000.
Converting representative fraction scale (RF) into linear scale
NOTE:
- Scales used on maps can be representative, linear or statement.
- Scales are important as they enable us to find actual distance on the ground.
- They also enable us to determine details presented by a map. This is determined by the size of maps.
- The size of maps is determined by scale.
- This can be:
- Small scale maps -this is a map that has a scale larger than 1:1000,000.
- Medium scale maps – this is a map whose scale range from 1:25,000 to 1:50,000.
- Large scale maps -this is a map with a scale range from 1:25,000 to 1:2000 and below.
- Determining distances and areas of places on a map using scales
Measuring distances on a topographical map
- Measuring distance on a map enables one to determine the distance between two points or places. The distance is measure using scale. The distance measured is either straight or curved, for example, a river, a road or a railway line.
- Equipment used to measure distance on a map. They include:
- A ruler.
- A string.
- A piece of paper with straight edge.
- A pair of dividers.
- Factors that determine the choice of the methods to be used in measuring distance on a map.Whether long, short , straight or curved.
Measuring distance a long a curved line
- On maps there are winding routes between two points like in case of roads, rivers and railways.
- Such features form curved lines when required to determine the exact distances.
- Various methods are used to measure or determine determine the distance such as:
- Using a piece of string.
- A sheet of paper.
- Pair of dividers.
Calculating area of Irregular objects
- Maps cover different places and features on the ground. Some features on maps such as forest, swamps and lakes have irregular shapes. The area covered by these features needs to be calculated.
- When calculating the area for such features we can use:
- Use of rectangles and triangles or division method.
- An irregular area is divided into smaller regular shapes such as triangles and rectangles and circles depending on the shape of the feature provided on the maps.
- Calculate the area of each shape.
- Add the areas to come up the total area of the irregular shape.
- Use of strips.
- It involves dividing the area into rectangular strips of the same width.
- The area of each strip is calculated separately.
- The areas of all the strips are added together.
- For example, in the following field in a map,
- Find the length of each strip, calculate the area of each and add all the areas of the rectangle strips.
- Use of grid squares.
- This methos is used in most topographical maps which always have grid squares formed by eastings and northings and they are drawn to a scale of 1:50,000 with each square representing an area of 1km2.
- To calculate area of an irregular shape on the map, use the following procedure.
- Mark complete squares and record their number, multiply the total number with 1km2.
- Calculate half squares using different marks, the total number of half squares should be divided by 2 and then multiplied by 1km2.
- Add the total area of complete squares to the total area of the half squares to get the total area of the feature.
- Total complete squares =18
- 18 x 1km2 =18km2
- Total number of half squares =19
- Divide by 2= 9.5
- 9. 5 x 1km2 = 9.5km2
- To get total area of the shaped
- Add total area of complete squares to the total are of half squares =18km2 + 9.5km2 =27.5km2.
Methods of representing relief on topographical maps
- Relief is the physical appearance of the land surface in terms of shape, size, height above sea level (elevation), and slope.
- Earth's surface consists of water bodies, landforms, and rocks.
- Relief is the difference between the highest and lowest elevations.
- Features are represented using different methods on topographical maps
Ways in which vegetation is represented on a topographical map
- Colouring – different colours are used to represent different types vegetation.
- Symbols – different symbols can be used to represent different types of vegetation such as trees, crops among others.
- Text label -labels with text explaining the type of vegetation can be used.
Interpreting Physical features on a map
- Topographical features have numerous physical features indicated on them and represented differently.
- The relief features are widely shown by means of contours.
- Contours on the maps occupy patterns with respect to the shape of the landforms (relief features).
- Relief on topographical maps are represented using different lines.
- The lines are arranged differently depending on the type of relief being represented
- Relief feature Descriptions.
- Lines showing a hill are represented by concentric circles (moving towards the centre) The circles indicate elevation of the hill, with the smallest circle at the top of the hill and larger circles at the lower elevation
Lines showing a ridge are represented by contour lines that form a sloping line of high ground. The contour lines forming a ridge tend to be U-shaped or V-shaped, with the closed end of the contour line pointing away from high ground.
These lines are known as Hachures. They are short lines used to indicate steep slopes or depressions.
Lines representing plains or flat areas on a topographical map are represented by widely spaced contour lines.
Lines used to show cliffs appear to be close to each other or cross each other.
