Talk to your partner. What do you think about this video? What animals can you see? Do you think our planet is wonderful? Why?

 

Do you know the meaning of 'biodiversity'? Can you find on the Internet how many species live in our planet nowadays?

 

Activity 1. Now watch this video:

Tree of Life BBC

Answer these questions:

1) What has done modern genetics? 

2) How did the life start? Where?

3) Order these animals following the tree of life: dinosaurs - mammals - cells - amphibians - reptiles - birds - sponges

 

Activity 2. Read this sentence: 

‘Nothing in Biology Makes Sense Except in the Light of Evolution’
(Theodosius Dobzhansky, biologist and evolutionist, 1973)

Talk to your partner: What does he mean with that sentence? Why do you think evolution is important?

Click on the top botton 'Endemic' to learn more about endemic species.

 

Extension. Why are Darwin's finches that important? How long was the Darwin's voyage on board HMS Beagle? Do a research on the Internet.

 

Activity 3. Look at this picture: http://www.diarioanimales.com/wp-content/uploads/tarsero-fantasma.jpg

Read this article about Neo-Darwinism: https://en.wikipedia.org/wiki/Neo-Darwinism

What are the differences between Darwinism and Neo-Darwinism?
