Answer 1

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..
