Q.1
Darwin's ideas were not well recieved when he published them inWhich of the following is a reason why?
  • He was not a trained scientist so other scientists would not believe him
  • He had upset the top scientists of the time so they persuaded everyone that his theory was rubbish to get their revenge
  • His book was so boring that no-one was able to read it
  • His ideas contradicted religious ideas about the Creation
Q.2
Why is there always variation in any population?
  • Half of the genes come from the mother and half from the father
  • Genes are all changed during sexual reproduction
  • Cosmic radiation damages genes in the sperm and egg cells
  • Because of natural selection
Q.3
The structural similarities between the flippers of whales and the arms of humans are used to show what?
  • The human species began life in the oceans
  • Humans and whales have a common ancestry
  • Whales are older than the human species
  • Whales evolved from the human species
Q.4
What might happen to an individual that is not well suited to its environment?
  • It could die before it has had the chance to reproduce and its genes will not be passed on
  • It will be helped by other animals of the same species
  • It will learn to be successful and pass on its genes to the next generation
  • A hunter will catch and eat it
Q.5
A variation in a plant creates a variety that has seed pods that 'explode' when touched by an animal. How could this lead to natural selection of this characteristic?
  • The seeds would be scattered further from the plant
  • The animals like the feeling and will brush past the plant more, scattering more seeds
  • The seeds fly through the air which activates more of them
  • The seeds fly higher and when they hit the ground, they go in further meaning more will grow
Q.6
Darwin's theory of evolution was based on what?
  • The disuse of body structures
  • The transmission of acquired characteristics
  • Natural selection
  • Mutagenic agents (things that cause mutations) in the environment
Q.7
Darwin's theory of evolution by natural selection failed to explain which of the following options?
  • There is less variation in a population every generation
  • New genetic varieties can appear in a population every generation
  • Populations of similar species could live in the same habitat
  • None of the above
Q.8
Variation in a population of dark brown beetles in a public park creates a green version. In which of the following situations would a positive natural selection be most likely to occur?
  • On a park bench
  • On trees with light colored bark
  • The beetles live entirely on the grass
  • The beetles live on the grass but find their food on the paths
Q.9
The example of dark peppered moths living in or near to British industrial cities following the Industrial Revolution, whilst light ones live in the countryside, shows what?
  • A change in an environment can result in the evolution of species living there
  • Evolution occurs so slowly that it is not possible to determine that it has happened in less than a million years
  • The environment in or near these cities has always favored dark colored moths
  • There is a better supply of food for dark moths in cities
Q.10
Fossils have been used to support Darwin's ideas. Fossils of which of the following animals are often used?
  • Horse
  • Dog
  • Cat
  • Rabbit
