Evolution Basics Which of the following things are likely to cause evolution in a population? Try to keep all causes of evolution in mind. The thickness in fur coat for particular small mammal is determined by the average temperature in its environment. Over time, the environment gets warmer. A mutation introduces a new wing color in a group of butterflies. A flood washes away 3/4 of a population of ground squirrels. Individuals migrate between 2 populations that have the same gene pool. Within a lizard population, there is genetic variation in the length of the tail. The neighborhood cats chase the lizaards, and have an easier time catching the ones with long tails. O 0OO0

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
