20
Q

Describe a hybrid

A

Infertile offspring produced by two different species

21
Q

What is the definition of fertile?

A

Can reproduce

22
Q

What is the definition of variation?

A

Difference in characteristics

23
Q

What are the two causes of variation?

A

Genetics

Environment

24
Q

What is the definition of a causation?

A

Where one thing is caused by another

25
Q

What does it mean by ‘concordant results’?

A

Similar results

26
Q

How can you make sure you have valid results?

A

Fair test
Measure what you are meant to measure
Compare to secondary evidence (textbook, internet etc.)

27
Q

What is continuous variation?

A

When a variable can have any numerical value - normal distribution curve
Eg. height, weight, heart rate

28
Q

What is discontinuous variation?

A

Not a continuous range - discrete data

Eg. gender, blood group

29
Q

What is artificial selection?

A

Where man selects

30
Q

What is speciation?

A

Development of a new species

31
Q

How does speciation happen

A

Two populations of the same species are split by physical barriers

Populations adapt to new environments

32
Q

Extreme environments

A
  • Deep sea vents- Angler fish
  • Volcanic vents- Chemosynthetic bacteria
  • Polar regions- Polar bears, penguins
33
Q

How are Angler fish adapted?

A

-rod shaped spine that gives off light and attracts prey

34
Q

How are Chemosynthetic bacteria adapted to volcanic vents

A

-Bacteria use chemicals from the vents to chemosynthesise

35
Q

How are polar bears adapted to the polar regions

A
  • Compact round shape with a small surface area compared to volume
  • Thick layer of blubber for insulation
  • Thick hairy coats trap a layer of warm air next to the skin
36
Q

How are penguins adapted

A
  • Thick layer of insulating fat
  • Oily feathers to shed water and reduce heat loss
  • Huddle together in groups
  • Streamlined body so they can swim fast and catch fish
37
Q

What is natural selection?

A

Survival of the fittest

Some individuals or more able than others to compete for resources as they are better adapted to the environment

38
Q

Evidence to support evolution

A

DNA research

Resistant organisms

39
Q

DNA research

A
  • Evolution suggests all organisms evolved from shared common ancestors
  • Closely related species diverged more recently
  • Scientists have found that organisms that diverged more recently have more similar DNA
40
Q

Resistant organisms

A
  • Poison warfarin was used to kill rats
  • A certain genes gives rats resistance to this
  • These rats are more likely to survive and breed
41
Q

How the scientific community validates evidence

A
  • Publish their work in scientific journals
  • Other scientists read and review the work
  • Repeating experiments to try and get the same results
  • Scientific conferences
42
Q

Why is accurate classification not always easy?

A
  • Not all organisms ‘interbreed’ like it says, some reproduce asexually but are still the same species
  • Many duck species can interbreed to produce fertile hybrids
  • There can be lots of variation within a species- eg in dogs
  • Ring species
43
Q

Organisms are the same species if…

A

They can interbreed to produce fertile offspring

44
Q

How does the binomial system help to conserve species

A

Easy to presume two similar looking organisms are the same species when they’re actually different

This could mean only one species is protected whilst the other becomes extinct

45
Q

How does the binomial system help to identify species

A

Avoids confusion where common names mean different things in different places

46
Q

How does the binomial system help to study species?

A

By identifying and naming species, scientists can share information on them

47
Q

How has the binomial system helped scientists?

A
  • Identifying species
  • Study species
  • Conserve species
  • Target conservation efforts
