Chapter 23, Problem 3CQ
Summary Introduction
To determine: The way by which genetic drift results in evolution.
Introduction: Genetic drift can be defined as a process in which a change occurs in the frequency of an existing variant of genes in a particular population. It occurs due to random sampling of living organisms.

- Natural Selection: you noticed a worms population displaying metamerism evolved from non metameric ancestors. Explain how this happened via natural selection. Mention key points necessarily used to describe evolution by natural selection.arrow_forward. The Process of Evolution by Natural Selection – Be able to explain the process of evolution by natural selection as it applies to a specific living thing using the outline below: Natural variations caused by random mutations (adaptations) in DNA exist within populations. Those with helpful adaptations survive an environmental change (maybe a predator.) The survivors breed, passing on the inherited mutation (adaptation) to offspring. The resulting population has more of the successful inherited mutation (adaptation) than the original population. Phylogenetic Trees Infer evolutionary relationships of living things by interpreting phylogenetic trees. Know the divisions of hierarchical classification. (DKPCOFGS) c. Differentiate between homologous and analogous (caused by convergent evolution) structuresarrow_forwardDefine genetic drift and how does it contribute to the evolution of a population?arrow_forward
