What is evolution?
It is a change in environmental characteristics of a population over time through natural selection, and this results in a new species
It is a change in inherited characteristics of a population over time through natural selection, and this results in a new species
It is a random process that happens over a few years
Why is 'survival of the fittest' associated with natural selection?
Within a population, individuals who have a selective advantage will survive, while others die out
They are the most physically fit individuals within a population
They are individuals with certain genes that give them no selective advantage
Which other scientist's work influenced Darwin's ideas?
Lamarck
Attenborough
Wallace
Why was the theory of evolution through the process of natural selection controversial?
People didn't like Darwin's ideas because they had heard them before
It went against many religious beliefs
It opposed many other scientists' ideas
How can new species be created?
Genetic variation, natural selection and homeostasis
Genetic variation, environmental variation and speciation
Genetic variation, natural selection and speciation
Why are fossils used to prove evolution happens?
Fossils are always created during any environmental conditions
They are nice to look at
They provide evidence of different species from a long time ago. These species may be now extinct
Why is the fossil record incomplete?
As not all fossils have been found, they may have been damaged, or conditions may have prevented them from being created
People sell fossils they have found
Fossils take a long time to form
Why do animals become extinct?
Animals become extinct because they can't find food
They become extinct because of predators, disease, hunting and climate change
Animals can't fly
How do bacteria become resistant to antibiotics?
Bacteria have always been resistant to bacteria
Mutations can lead to resistance, as these strains survive and reproduce rapidly
If they are never treated with a particular antibiotic
How can antibiotic resistance be reduced?
Never complete the full course of antibiotics prescribed by a doctor
Take antibiotics at every opportunity possible, even for a viral infection
Only take when really needed, complete the full course and use less in agriculture
