Questions and Answers
Natural Selection - ✅✅Organisms with more advantageous traits for their environment survive and
reproduce more often (This causes traits in the population to change over time).
Overproduction of offspring - ✅✅Organisms produce more offspring than needed to sustain the
population.
Struggle To Survive - ✅✅Hunger, disease, and predators all make it difficult for organisms to survive.
Successful reproduction - ✅✅The best adapted to their environment are likely to have many offspring
that survive.
Adaptation - ✅✅A trait that helps a population survive (Polar bear's white fur helps them hide from
prey in the snow).
Population - ✅✅A group organisms of the same species living in a particular area at the same time
Trait - ✅✅A characteristic that an organism can pass on to its offspring through its genes.
Individual - ✅✅One organism
Genetic Variation - ✅✅Any difference between individuals of the same species.
Darwin's Theory - ✅✅Organisms born with the best adaptations survive and pass on their traits to
offspring. Organisms without these adaptations die and do not reproduce. Over time, the population
changes as more organisms inherit the adaptation.
, Artificial Selection - ✅✅Human interventions in helping to produce desired traits in domesticated
animals
Mutation - ✅✅The process in which DNA changes result in new alleles
Extinct - ✅✅When the last of a species dies
Biological Fitness - ✅✅A species that is most suited to survive in a certain type of environment.
An example of artificial selection - ✅✅Breeding of all dogs today.
examples of Adaptions - ✅✅Fish gills, bird wings, thick fur on arctic animals are all......
species - ✅✅A group of similar organisms that can breed and produce fertile offspring.
fossil - ✅✅A trace of an ancient organism that has been preserved in rock
adaptation - ✅✅A trait that helps an organism survive and reproduce
evolution - ✅✅Change in a kind of organism over time; process by which modern organisms have
descended from ancient organisms.
scientific theory - ✅✅A well tested concept that explains a wide range of observations
natural selection - ✅✅Process by which individuals that are better suited to their environment
survive and reproduce most successfully; also called survival of the fittest
variation - ✅✅Difference among members of a species.
