False Answer False What has come to be known as the "modern evolutionary synthesis" began in the 1930s and 1940s. What did it involve? a. The incorporation of the ideas of developmental biology into evolutionary theory b. The development of statistical analysis in evolution c. The fusion of biology and chemistry d. The integration of genetics, systematics, and paleontology, allowi...

modern synthesis - describes how evolutionary processes can affect a population'a genetic makeup, and, in turn how this can result in gradual evolution of populations and species Microevolution - population changes over time Macroevolution - processes that gave rise to new species and higher taxonomic groups what is the difference between microevolution and macroevolution? - microevolution is evolution at the population level (i.e. where tarts within populations get more/less prevalent...

The hypothesis of punctuated equilibrium was based on what model for speciation? - peripatetic speciation What is true microevolution? - it is the kind of evolution that can change the relative abundance of a particular allele in a gene pool over the course of generations A relatively small number of Amish immigrants came to this country in the 1700's. They have since greatly increased their number while remaining largely segregated from the rest of the population. Polydactyly (having ...

What is microevolution? - The change in allele frequencies that occurs over time within a population. What is macroevolution? - Major evolutionary changes over time, the origin of new types of organisms from previously existing, but different, ancestral types. What is a species? - A group of populations whose members possess similar anatomical characteristics and have the ability to interbreed. What is allopatric speciation? - The formation of a new species in populations that are geographi...

During an individual organism's lifetime, which of these is most likely to help the organism respond properly to changes in its environment? A) microevolution B) change in allele or gene frequency C) change in gene expression D) change in average heterozygosity - ANSWER C) change in gene expression If, on average, 46% of the loci in a species' gene pool are heterozygous, then the average homozygosity of the species should be A) 23%. B) 46%. C) 54%. D) There is not enough inf...

What is marine ecology? correct answers The study of interactions between an organism and their abiotic and biotic habitats. And how these interactions affect the distribution and abundance of organisms What is the difference between micro and macroevolutio? correct answers microevolution: changes in genetics over time that lead to new phenotypic features or life history macroevolution: changes in genetics over time that lead to a new species What is commensialism? correct answers A symbi...
