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 ...

Shoot system - consists of two portions: the vegetative (non-reproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant, which include flowers and fruits. The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. Root system - which supports the plants and absorbs water and minerals, is usually underground. Meristematic tissue - either undifferentiated or incompletely differentiated, and they ...

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...

How is the field of Biology organized hierarchically? - Evolution - the process of change that has transformed life on earth Adaption - the change over generations to better fir the environment both behavioral and physical How does natural selection work? - -Individuals compete for limited resources to survive -Some have better chance than others -Varieties with increased chance in survival continue to reproduce and pass on genes -Greater number in next generation have the characteristi...
