Topic 6 - More About Evolution

Question 1

Why did not everyone agree with Darwin’s theory?

Answer 1

• It went against common religious beliefs about how life on earth developed
• There was not enough evidence to convince scientists (not enough studies done)
• Darwin couldn’t explain why the new useful characteristics appeared or hoe they were passed on

Question 2

What was Lamarck’s hypothesis about evolution?

Answer 2

Changes that an organism acquired over it’s lifetime are passed on to its offspring. If a characteristic is used a lot by an organism, it would become more developed during its lifetime, and the organism’s offspring would inherit the acquired characteristics

Question 3

How can you fins out which hypothesis is right?

Answer 3

Finding evidence to support or disprove one

Question 4

Why was Lamack’s hypothesis rejected?

Answer 4

Experiments didn’t support his hypothesis. If a hamster’s fur is dyed, it’s offspring don’t get the colour

Question 5

Why was Darwin’s hypothesis accepted?

Answer 5

The discovery of genetics supported his idea by providing an explanation of how organisms born with beneficial characteristics can pass them on.
