U5 Revealing nature
Starting out+Understanding ideas
What do you expect from the title
to make known something that was previously secret or unknown
Where does this page come from
What do you know about these animals
The Komodo dragon is the
largest lizard in the world.
It can grow to three metres
in length and can weigh
about 135 kilometres.
Despite its size and weight,
it can run for short distances
at up to 20 kilometrs per hour.
As one of the oldest sea animals in the world, the nautilus has hardly changed in about 500 million years, and that is why it is often given the name “living fossil”.
The duck-billed platypus is a small egg-laying mammal (up to 60 cm in length) found only in Eastern Australia including Tasmania. As its name suggests, it has a mouth that looks like a duck's bill, while its thick fur and flat tail are similar to those of a beaver.

What do you know about him
While-reading
Read the passage and talk about your understanding of the title.
Most commonly, people believe that a journey means a trip from one place to another, especially over a long distance and literarily a journey refers to the process by which something gradually changes and develops. The title may indicate that Darwin's research work leading to his discovery of evolution and the origin of species took quite a long time and great efforts, determination and courage to achieve.

Why did Darwin not publish his Theory
of Evolution until 1859, about twenty
years after his discovery
After-reading
Think and share
1 Why were many people “shocked” by
Darwin’s theory
At that time, many people believed that all
species had appeared on Earth at the same time
and had not changed since, but Darwin’s theory
proposed that living things, including humans,
had evolved from lower forms of life, which, as
a result, shocked many people.
2 What kind of person was Darwin according
to the passage
Darwin was a determined man. He had strong
curiosity and interests in science and was good
at thinking and making discoveries.
3 How do you think the human species will evolve
in the future
4 What have you learnt about the spirit of
scientific exploration How can this spirit help
you in your life and studies
