Question
Chapter 1, Problem 7PDT
Summary Introduction
To explain: The ways in which phenomenon such as natural selection, gene flow, genetic drift, and mutations cause populations, species, and higher taxa to evolve.
Introduction: Evolution is very much important for continuity of a species. It is a natural and continuously going on process that ensures better survival of a species. Different factors, over a long time span, play an important role in the evolution of one species.

Students have asked these similar questions
how do scientists support the theory of evolution? use the terms evolution, natural selection, vestigial structures, homologous structures, DNA, adaptations and fossil
How can a shift in the proportion of genes in a population could lead to the evolution of a new species?
Explain why evolution happens to a whole population rather than to a single individual.
ln three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance.
