Why do penguins waddle?

Penguins are lovable creatures that can instantly be recognised by their distinctive walk, or ‘waddle’. Today we discover the scientific theory that explains why penguins waddle.

펭귄은 뒤뚱거리는 걸음걸이만 봐도 금방 알아 챌 수 있는 사랑스러운 동물입니다. 이번 시간에는 펭귄이 뒤뚱거리고 걷는 이유를 설명해주는 과학 이론을 들어보겠습니다.

Before you listen

1) How many words can you think of that describe penguins and the way that they walk?

2) How can scientists compare animals today to animals in the past?

Listen to the audio and take the quiz.

Bolam
안녕하세요! Listen Here에 오신 것을 환영합니다. 이 코너에서는 여러분이 영어 뉴스를 잘 이해할 수 있는데 필요한 표현을 알려드릴 거에요. 저는 손보람입니다.

Tom
And hello again everyone, I'm Tom. Today we are discussing penguins and asking the question 'why do penguins waddle?'

Bolam
'Waddle' – 뒤뚱 뒤뚱 걷는다는 뜻이죠.

Tom
Let's listen to the first part of today's clip from BBC Radio 4's Today Programme.

Bolam
좋은 생각이에요! 진행자가 런던 동물원의 펭귄 구역에서 뒤뚱거리는 걸음걸이에 대한 과학적인 실험에 대해서 이야기 하고 있습니다. 펭귄이 걷는 모습을 묘사하기 위해 어떤 단어를 사용하는지 들어볼까요?

Presenter
With its tiny legs and stiff, upright posture a penguin has a waddle that's more than a little ungainly. But by installing a high-tech track in London Zoo, scientists will measure every tiny movement the birds make.

Bolam
'Posture'는 자세를 뜻합니다. 이 단어는 사람들이 서 있는 모습에 대해서 묘사할 때 자주 쓰입니다. 진행자는 펭귄의 자세를 'stiff' 경직된, 'upright' 꼿꼿한..이라고 묘사했습니다.

Tom
And she also describes the waddle as 'ungainly'.

Bolam
'Ungainly' 어색한..이라는 뜻으로, 'awkward'나 'clumsy'와 비슷한 말입니다.

Tom
The presenter actually uses a phrase before 'ungainly'. But, what is it? Listen again after 'penguin has a waddle… '

Insert
With its tiny legs and stiff, upright posture a penguin has a waddle that's more than a little ungainly.

Tom
She said 'that's more than a little ungainly'.

Bolam
'More than a little'은 이 문장에서 'quite'라는 의미로 쓰였습니다. Why doesn't she say 'quite ungainly'? That's much simpler!

Tom
Well, we often say this when we want to suggest something slightly negative in a more positive manner. Plus, the rhythm sounds good. Say it with me to practise! 

'a little'
'more than a little'
'more than a little ungainly'

Can you give us an example now?

Bolam
Hmm… Working with you is more than a little difficult, sometimes! 진행자에 따르면 과학자들은 추적기를 이용해서 펭귄의 움직임을 기록하고 있고, 이 데이터를 과거의 데이터와 비교한다고 합니다.

Tom
We can find stones or rocks with animal remains inside them. What's the name for these? Let's listen again!

Insert
But by installing a high-tech track in London Zoo, scientists will measure every tiny movement the birds make. The researchers will then compare this data with penguin fossils.

Bolam
'A fossil'은 화석입니다. 잠시만 쉬어 갈게요. 지금까지 현대의 펭귄은 'stiff, upright posture' 와 'tiny legs'를 가지고 있다는 이야기를 들었습니다. 그렇다면 현대의 펭귄과 과거의 펭귄은 똑같을까요? 이야기를 마저 듣고 알아봅시다!

Insert
The researchers will then compare this data with penguin fossils. They think that the ancient birds didn't waddle and had a more horizontal posture with different leg anatomy. The scientists suspect that as modern-day penguins became better adapted to swimming, they became more clumsy on land.

Tom

So, they aren't the same! We've heard how modern penguins have an upright posture. Penguins in the past were the opposite! They had a horizontal posture.

Bolam
'Horizontal'은 수평의..라는 뜻입니다. Which means they were lying flat!

Tom
Right! Their legs have probably adapted over time as their posture changed.

Bolam
'Adapt'는 적응하다..는 뜻으로 'adapt to' + [명사/동사-ing]의 형태로 자주 씁니다. 마지막 문장을 다시 한번 들어볼게요. 펭귄이 무엇에 'adapt to' 적응했나요?

Insert
The scientists suspect that as modern-day penguins became better adapted to swimming, they became more clumsy on land.

Tom
So, penguins adapted to swimming. This means the anatomy, or structure, of their legs changed to become more suitable for water.

Bolam
And that's why they're 'clumsy', 어설프군요!

Tom
Exactly!

Bolam
Join us next time to learn more! Say goodbye, Tom!

Tom
Bye everyone! See you next time!

Language features

horizontal / upright posture

Posture relates to position. It describes someone’s position when they are standing or sitting.

  • You should sit up straight at your desk! A bad posture can cause back pain.

Horizontal describes something which lies flat or level with the ground. The opposite of horizontal is vertical. Upright is a synonym of vertical. It’s commonly used when referring to posture.

to adapt

To adapt means ‘to change in accordance with something’.

  • After I had a baby I adapted my bike – it now has two seats instead of one!

To become adapted describes the process of changing when change is influenced by important factors.

  • Otters have become adapted to cold water. They have thick fur which keeps them warm.

anatomy

Anatomy is a noun used to refer to the structure of the body.

  • The anatomy of a shark is perfect for hunting in the sea. They have sharp teeth and can breathe underwater using gills.

The subject name for the study of bodily structure is also anatomy.

  • I need to leave or I will be late for  my anatomy class!
