Climate change and evolution

I can explain how climate change could affect the evolution of species and lead to extinctions, and some actions we can take to help prevent the loss of species.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Variation within a species may affect how well different individuals can survive when environmental conditions change
  2. This leads to natural selection, favouring individuals better adapted to survive and reproduce in the new conditions
  3. Climate change could result in natural selection of individuals that are more tolerant of drought and high temperatures
  4. Some species may not evolve quickly enough to keep up with climate change and could become extinct
  5. Humans can use various methods to help protect against species loss due to climate change, e.g. selective breeding

Keywords

  • Variation - Differences between members of the same species.

  • Natural selection - Organisms that are better adapted to their environment are more likely to survive, reproduce and pass on their genes to their offspring.

  • Climate change - Climate change is a long-term shift in weather patterns.

  • Extinction - Extinction is the permanent loss of a species

  • Selective breeding - The process in which humans choose individuals with desirable traits and mate them in order to make offspring with these desirable traits.

Common misconception

All species will be able to evolve to cope with climate change.

The lesson explores why not all species will be able to evolve fast enough to adapt to the pace of climate change.

The predictions about extinctions may feel bleak. It's important to give pupils active hope by exploring things we can all do to make a difference; some of these are explored briefly in the third section of this lesson, and in much more detail in other climate change lessons.

Q1.
True or false? Fossils provide evidence that the characteristics of species change over generations.

An image in a quiz
Correct answer: True
False

Q2.
What can we conclude from the fossilised leg bones of horses?

An image in a quiz
Correct answer: Ancestors of the modern horse had some different features.
Horse leg bones have stayed the same during evolution of the horse.
There are no similarities between the modern horse and its ancestors.
We cannot conclude anything about horse evolution from this evidence.

Q3.
Fossils provide evidence that the characteristics of species change over generations. These gradual changes are called…

Correct answer: evolution.
extinction.
reproduction.
selective breeding.

Q4.
The cats are all members of the same species. But there are differences in their characteristics. These differences are an example of…

Correct answer: variation.

Q5.
Most scientists believe that the evolution of species can be explained by a process of natural .

Correct Answer: selection

Q6.
If environmental conditions change and a species does not evolve fast enough to adapt to the change, this can cause all members of the species to die out. The species has then become .

6 Questions

Q1.
What is climate change?

A short heatwave.
Correct answer: A long-term shift in weather patterns.
Seasonal differences in weather between spring, summer, autumn and winter.
The differences in temperature between day and night.

Q2.
What can we conclude from the graph shown?

An image in a quiz
Correct answer: Global temperatures are now higher than the global mean of 1951-1980.
The trend is an overall decrease in temperatures since 1910.
There is total lack of agreement in the data from different agencies.
Year-to-year fluctuations means we cannot see any trend in the data.

Q3.
Match each of the following scientific terms to its correct definition.

Correct Answer:extinction,the permanent loss of a species when all members have died out

the permanent loss of a species when all members have died out

Correct Answer:migration,the movement of a species to a new area

the movement of a species to a new area

Correct Answer:selective breeding,a human process done to change the characteristics of a species

a human process done to change the characteristics of a species

Correct Answer:variation,the differences between members of the same species

the differences between members of the same species

Q4.
True or false? All species will be able to survive climate change by migrating to new areas where the conditions remain suitable for them.

True
Correct answer: False

Q5.
The Bramble Cay mosaic-tailed rat went extinct because of climate change. Which statement about this species is correct?

An image in a quiz
It could be brought back using selective breeding.
Correct answer: It could not evolve quickly enough to adapt to the changing climate.
It is the only species likely to go extinct because of climate change.
It will come back to life if the climate changes back to how it was before.

Q6.
Match each action to how it helps to reduce extinctions.

Correct Answer:selective breeding,can change some species to be more resistant to climate change

can change some species to be more resistant to climate change

Correct Answer:storing DNA in gene banks,may enable us to bring some species back from extinction

may enable us to bring some species back from extinction

Correct Answer:eating less meat,reduces agricultural emissions so reduces climate change

reduces agricultural emissions so reduces climate change

Correct Answer:travelling by electric bus,reduces fossil fuel emissions so reduces climate change

reduces fossil fuel emissions so reduces climate change
