Is this experiment testing the evolution of trait or evolution of a species?
firstly you should know what is evolution ?
Definition: The process by which different kinds of living organism are believed to have developed from earlier forms during the history of earth. In short, all living organisms are developed from simillar earlier forms, which occured by undergoing minor changes with the change in the environmental conditions.
Trait evolution describes as a change in inherited traits of populations through successive generations. When living organisms reproduce, they pass on to their progeny a collection of traits.
Experimental evolution is one of the best choice for the development of live attenuated vaccines against viral and bacterial diseases, such as polio, tuberculosis, yellow fever, measles, mumps, and rubella. Thus, experimental evolution has contributed to save millions of human lives which is started after discovery Darwins theory of evolution.
Two different ways in which adaptation can arise in experimental evolution. One is via an individual organism gaining a novel beneficial mutation. The other is from allele frequency change in standing genetic variation already present in a population of organisms.
Shortly the vaccines development is one of example for an experiment testing for the evolution of traits or species.
Why are quail a useful subject for this experiment?
Quail are most useful for evolution studies. Since they eat many kinds of seeds are used in palatability studies. They are important models for reproductive studies. A study conducted in Japan, Quail egg used for the determination of egg quality by checking the strength of the shell.Also Darwins theory of natural selection, finches changes are observed in Quails.
what kind of change occurred over time and why?
In evolution changes are occuring over time. Darwin theory expalins the changes are occuring over time. for example Darwins theory of natural selection, in this the eagle can find and eat easily white moths on black rock easily,, but black moths survived ,, ie theory of natural selection.
next theory of survival of fittest - the organism best adjusted to their environment are the most successful for surviving and reproducing. example: the quail changes their sharpness of finches depending on the availability of the feeds. so that it can survive by eating insects - earlier it was seed eating later changed. Plants also undergo changes depending upon the environmental changes like sunlight availability,water etc..

Please answer the following questions! 1) Define the four forces of evolution, making sure to highlight how they lead to change in a population. 2) Do you think sexual selection should be considered a fifth force of evolution? Why or why not. 3) Define cline and describe one example of a cline (this can be from the course material, or from outside sources, Explain how the trait is distributed and how it relates to the environment. 4) You have just...
a. Why is heritability necessary for natural selection? How would you expect a trait for which there is no resemblance between parents and offspring to change over time? b. Why is differential success among organisms with different variants of a trait necessary for natural selection? How would you expect a trait for which there is no differential success to change over time?
Summarize Darwin's theory of natural selection and evolution of species. Why is this theory important for scientific psychology. Support your view.
1. What is often true about the relative rates of phenotypic evolution of sexually selected traits vs most other kinds of traits? 2. In the good genes model, why does a male trait have to be costly in order for the female preference to be maintained by natural selection? 3. Explain the Fisherian (runaway)model of sexual selection –what generates correlations between female preferences and male traits. What kind of experimental observation would support the model? 4. Explain the concept of...
Evolution by natural selection, initially described by Charles Darwin, is the theory that explains how a population’s inherited traits change over time and describe why organisms must adapt to their environments. Evolutionary theory can explain how specialized features develop in different species.
A species experiences prolonged directional selection, resulting in the evolution of larger body size. What other changes to that species' life history traits are likely to accompany this change in body size?
Evolution: (taken from "Easier Being Green" in National Geographic) The oblong-winged species of katydids was discovered in 1770's. Although the majority of katydids are green, a fraction displays unique bright colors of yellow, orange and hot pink. Entomologists belief the colors are symptoms of erythrism, an anomaly similar to albinism. Although the hot pink color is the dominant trait, these individuals are by far the fewest in number, closely followed by the orange and yellow. The green katydids, even though...
5. In the North Pole species of elves, the trait for pointed ears (P) is dominant over rounded ears (p), and the trait for large feet is (F) is dominant over small feet (f). A female elf with pointed ears and large feet (heterozygous for both traits) has married a handsome elf with pointed ears (heterozygous) and small feet. They are planning to start a family. a. List the genotype of the parents: b. What will be the distribution of...
a) Why do species that reproduce sexually have more genetic variation than species that reproduce asexually? b) Why is it difficult to use genetics to predict exactly how tall someone will be? c) Many prokaryotes reproduce asexually using binary fission. Why is it impossible for a prokaryote to use the process of meiosis for reproduction? d) Monosomy is a genetic disorder. In this disorder, a person receives one gamete that has is missing a chromosome. This gives the person one...
Conditional probability. In an experiment with species A. pub and A. ali. Fungus could infect seeds of the two types of species, and at different rates. Species A. pub has fungus 25% of the time, while A.ali has fungus 50% of the time. Then randomly a subject selects a seed of one species. 1.What is the probability that it has the fungus. a.Calculate this using a probability tree b. Calculate with the law of total probability. Write that equation. c....
