evolution

Question 1

why are organisms so diverse?

Answer 1

• a response to the diversity of environments
• an evolutionary process to fill up the available ecological niches
  - natural selection: adapt/resist
  (may go extinct)

Question 2

a blind and creative process can

Answer 2

• include the success of humans who make conscious decisions in natural selection
• the narrow and specialised organisms which makes unintentional decisions in natural selection

Question 3

universal biological similarities

Answer 3

DNA & RNA (with universal biological similarities)

Question 4

what is surprising about life?

Answer 4

1. ingenuity
   everything is so perfectly and purposefully created/designed
2. unity
   everything shares a common ancestor
3. diversity
   everything is infinitely different yet so similar
   gradual modification

Question 5

Charles Darwin & Robert FitzRoy

Answer 5

Noticed a disproportionate number of finches
- noticed there is a lot of them but a lot of different finches with slight modification
- has one common ancestor but settled into different islands and different food sources so descended to become more adaptive to their environment niches
- ‘descent with modification’

Question 6

How do we explain the surprising factors?

Answer 6

Darin’s theory
‘The origin of species’ (1958)

variation + inheritance + selection = evolution

variation: a difference, not identical
inheritance: from parents to child
selection: nature selects quality / selective breeding (humans)

Question 7

Hypothesis

Answer 7

a ‘what’ statement
no explanation
what you think happened/will happen/ is happening

Question 8

Theory

Answer 8

a ‘why’ statement
an explanation of why something is happening
why you think something happened/ will happen/ is happening
