Answer and Explanation: Which of the following best describes evolution? a) It is the tendency for species to remain unchanged over successive generations. See full answer below.
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
Which of the following statements best describes macroevolution? Macroevolution is the same as microevolution, but includes the origin of new species.
Natural selection is the process through which species adapt to their environments. It is the engine that drives evolution.
Evolution is a process of gradual change that takes place over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Evolution. Evolution is change in the heritable traits of biological populations over successive generations. Adaptation.
Gene flow between populations must be interrupted. Which of the following statements correctly describes one aspect of the punctuated model of evolution? Species tend to change rapidly in a short period of time. You just studied 31 terms!
What is the difference between microevolution and macroevolution? Microevolution deals with changes in the gene pool of a single population. Macroevolution considers the broad pattern of evolutionary change over long periods of time and includes the origin of new groups.
Microevolution is defined as changes in the frequency of a gene in a population. These are subtle changes that can occur in very short periods of time, and may not be visible to a casual observer.
Evolution is the change in heritable traits of biological populations over successive generations. Evolutionary processes give rise to diversity at every biological organization level. All life on earth shares a common ancestor known as the last universal ancestor.
Evolution occurs with the change in gene frequencies of a population. The main forces of evolution are gene flow, genetic drift, mutation, genetic recombination and natural selection.
That's what evolution is: Animals change over time in order to survive where they live. So, fish evolved to have gills because they needed to be able to breathe underwater. Some animals evolved to have sharp teeth or big claws so they could kill their dinner.
