Learning goal 3: Identify the definition of evolution.A change in the genetic traits in a population over millions of yearsA change in the genetic traits in a population over many generationsA change in the acquired traits of an organism over its lifetimeA change in the acquired traits in a population over many generations

A precise definition of evolution is theMultiple choice question.change in physical characteristics of an individual in its lifetime.genetic change in a population over multiple generations.net change in population size over multiple generations.change in a phenotype toward a more advanced form of the trait.

Which of the following is the best definition for evolution? An environmental change that a species must adapt toA change in a species over a single generationA change in a species over many generationsA random mutation that is passed on from parents to offspring 2What is meant by the term ‘survival of the fittest’?Individuals at the top of the food chain will survive, while those at the bottom will die outLarger individuals within a population will survive, while smaller ones will die outIndividuals with a selective advantage within a population will survive, while others will die outIndividuals who work hard to become physically fit will survive, while others will die out3Which scientist proposed the same theory of natural section as Charles Darwin?Alfred WallaceJean-Baptise LarmarckRichard DawkinsGregor Mendel4Which of the following is not part of the process of speciation?Natural variation within a population Interbreeding between two speciesDifferent parts of the same population becoming isolated in different environmentsFormation of a geographical barrier within a population5Which of the following could be an example of ‘mimicry’ as protection from predation?A green caterpillar on a red flowerA red caterpillar with a bitter tasteA red caterpillar with a sweet tasteA green caterpillar on a green leaf

Darwin originally defined evolution as ______________________.Group of answer choicesdescent with modificationan individual's ability to adapt to its environmentthe passing of acquired characteristics to offspringa way to classify organisms based on morphological similarities

Learning goal 2: Determine the best explanation for how new variations in genetic traits arise in a population.Random mutations cause offspring to look radically different to their parentsIndividuals acquire new traits during their lifetimesIndividuals with harmful genetic traits die before they can reproduceRandom mutations cause changes in DNA with each generation

Define the term evolution and relate to life on earth
