What impact have humans had on plants and animals?

In this lesson, we will look at how humans have changed over time and use the theory of evolution to explain these changes. Learning how to make and use tools, shelter, fire and language has enabled humans to spread all over the world. We will start to look at the impact that humans have had on some species of plants and animals. You will need a piece of paper and a pencil for this lesson.

Evolution and Inheritance: Adaptation, Evolution and Human Intervention:

Use the PowerPoint below to support your learning.

The conditions for adaptation by natural selection has lead to evolution.

Living Fossils: Read through the information about what constitutes a living fossil and how some living
things have remained virtually unchanged. Does this mean these living things have never developed
mutations or does it mean those that did have become extinct? Which is a more plausible explanation?

Advantages and Disadvantages of Adaptation: Look at examples of how an adaptation can have both
advantages and disadvantages. You should cut and match the advantages and disadvantages of specific
adaptations in living things using the Advantages and Disadvantages of Adaptation Activity.

Evolution and Human Intervention: Through the understanding of DNA and genes, humans have affected the evolutionary process through selective breeding of plants and animals. Task: examine and sort the Selective and Cross
Breeding Cards into parent(s) and selectively bred offspring.
