Aug 15, 2020 · Scientists consider evolution a key concept to understanding life. Natural selection is one of the most dominant evolutionary forces. 19.1: Population Evolution Initially, the newly discovered particulate nature of genes made it difficult for biologists to understand how gradual evolution could occur. OpenStax: Biology Concepts textbook: CH11:EVOLUTION AND ITS PROCESSES, Professors can easily adopt this content into their course. Another evidence of evolution is the convergence of form in organisms that share similar environments. For example, species of unrelated animals, such as the arctic fox and ptarmigan (a bird), living in the arctic region have temporary white coverings during winter to blend with the snow and ice (Figure 11.12). Astronomy is designed to meet the scope and sequence requirements of one- or two-semester introductory astronomy courses. The book begins with relevant scientific fundamentals and progresses through an exploration of the solar system, stars, galaxies, and cosmology. The Astronomy textbook builds student understanding through the use of relevant analogies, clear and non-technical explanations ... Start studying OpenStax US History Ch. 8 Review Questions & Terms. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Aug 15, 2020 · Evolution is not purposefully adaptive; it is the result of various selection forces working together to influence genetic and phenotypical variances within a population. Key Terms linkage disequilibrium : a non-random association of two or more alleles at two or more loci; normally caused by an interaction between genes Jul 29, 2019 · Openstax does have chapter questions available, but I prefer to use reading guides which ask students to read the chapter, pausing to answer questions as they go. I have developed reading guides for several chapters and will add more as I go.

For questions regarding this license, please contact [email protected] Mutation is a change in the DNA sequence of the gene. A mutation can change one allele into another, but the net effect is a change in frequency. The change in frequency resulting from mutation is small, so its effect on evolution is small unless it interacts with one of the other factors, such as selection. Evolution has no goal of making faster, bigger, more complex, or even smarter species, despite the commonness of this kind of language in popular discourse. What characteristics evolve in a species are a function of the variation present and the environment, both of which are constantly changing in a nondirectional way.

The OpenStax Biology book has units and chapters that cover all of the major topics that one would consider for a general or introductory Biology course. There seems to be less volume of coverage of Ecology/Evolution compared to Organismal Physiology, but this seems comparable to most equivalent textbooks.

OpenStax: Astronomy textbook: 22.5 The Evolution of More Massive Stars, Professors can easily adopt this content into their course. Evolution is the change in a population’s genetic composition over time, specifically over generations, resulting from differential reproduction of individuals with certain alleles. Individuals do change over their lifetime, obviously, but this is development and involves changes programmed by the set of genes the individual acquired at birth ...

Another evidence of evolution is the convergence of form in organisms that share similar environments. For example, species of unrelated animals, such as the arctic fox and ptarmigan (a bird), living in the arctic region have temporary white coverings during winter to blend with the snow and ice ( [Figure 3] ). Aug 25, 2020 · Another important finding was the discovery of isotopes. During the early 1900s, scientists identified several substances that appeared to be new elements, isolating them from radioactive ores. Aug 15, 2020 · The evolution of species has resulted in enormous variation in form and function. Sometimes, evolution gives rise to groups of organisms that become tremendously different from each other. When two species evolve in diverse directions from a common point, it is called divergent evolution. Such divergent evolution can be seen in the forms of the ...

Every fall, the media starts reporting on flu vaccinations and potential outbreaks. Scientists, health experts, and institutions determine recommendations for different parts of the population, predict optimal production and inoculation schedules, create vaccines, and set up clinics to provide inoculations. The geological evolution of the icy moons and Pluto has been somewhat different from that of the terrestrial planets. Tidal energy sources have been active, and the materials nature has to work with are not the same. Aug 15, 2020 · 18.0 Evolution All species of living organisms, from bacteria to baboons to blueberries, evolved at some point from a different species. Although it may seem that living things today stay much the same, that is not the case—evolution is an ongoing process.
