Mechanism of Evolution

Which scientist came up with the idea of natural selection?

• Lamarck

• Lyell

• Darwin

• Malthus

Which best describes non-random mating?

• Organism from different populations mate and have a new offspring

• Organism from the same population that have similar characteristics have an offspring

• Organisms from one population have an offspring and move to a different population

What function does gene flow do in evolution ?

• It crops feeds species

• It doesn’t produce offspring

• It creates offsprings better prepared for the world

• It doesn’t prepare species for the world

In which form can macro evolution be discovered

• Thru experiments

• Rock layers

• land around volcanoes

• underground

Which best describes convergent evolution?

• It forms homologous structures

• It forms structures in different species that are similar

• Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.

What is convolution

• Two or more species rely on each other to evolve

• two or more species reciprocally affect each other's evolution

• Animals need each other to evolve

What is rated of evolution

• measurement of the rate of genotype change of species and organisms over a period of time.

• Changes in population size over time

• Measurement is Imigration over time

• Measurement of emigration over time

What is natural selection

• The prices that organism better adapted to their environment tend to survive

• Stronger organism survive longer

• Organisms that immigrate create new species

What is the founder effects

• the reduced genetic diversity which results when a population is descended from a small number of colonizing ancestors.

• population mates to created the next generation

• The adaptation of organism to their new environment

What is a reason and organism leaves a population

• Overpopulation

• No resources

• Fighting for food

• No mates

• All of the above.
