In early spring, dr. tom wilson notices that there is an equal distribution of long and short stemmed buttercups in the vacant lot across the street from his house as well as in his own backward. in the late summer he notes that there are mostly long stemmed buttercups in the lot, but mostly short stemmed buttercups in his yard. these observations are examples of what biological principle? develop a hypothesis to explain dr. wilson's observations.

Respuesta :

Hypothesis is an initial proposed explanation based on the first observation upon this situation.
In this situation, Dr. Wilson could make a hypothesis that short stemmed buttercups need more water and nutrients that could only be gotten from the soil provided in the yard.

The answer is natural selection. There is a natural selection happening about the long and short-stemmed buttercups.

 

EXPLANATION  

Natural selection is a process that happens in nature. It is a process where organisms holding specific genotypic traits that create them survive better in an environment. They can survive, reproduce, and also increase in several frequencies. In the end, they can transmit their qualities to succeeding generations.

 

Evolution is the process and event that take place for a long time, illustrating the gradual progression of changes, specifically in the hereditary arrangement of the biological population over succeeding generations. Natural selection and genetic drift are the two major mechanisms that are driving the evolution.  

 

Natural selection is a process in which heritable traits of an organism will either strengthen or weaken their chances in reproduction and survival. These characteristics are also favored than less advantageous characteristics. This theory is first proposed by the infamous Charles Darwin.

 

Natural selection itself is a process with outcomes in the progression of organisms. The evolution that is driven by natural selection is called adaptive evolution. Genetic drift produces some random changes in the frequency of traits inside a population. Meanwhile, an evolution that is driven by the hereditary meaning is called neutral evolution.

 

The hypothesis is that the long-stemmed buttercups genetics allow them to survive if they have enough water and nutrients, that is why they survive in the soil of the yard and not in the lot.
