Two 45 - 55 minute class periods. Students will learn about the timescale of evolution through the fictional evolution of humankindyears into the future into different sub-species that live in a complex relationship of predation and reproduction. They will also be introduced to the mechanisms that drive evolution, namely mutations and natural selection, through examples of some dramatic mutations such as the Blue Moon butterfly and relatively recent mutations in the human species such as the ability of adults to digest dairy products and the appearance of blue eyes.
Students will discuss the idea that human evolution has come to a halt, held by many researchers and currently under debate. They will also be introduced to the concept of genetic engineering. The movie "The Time Machine" will add interest and variety to the study of evolution.
Description of the Snippet: In the first of three segments, scientist and inventor Alexander Hartdegen travels with his Time Machineyears to the future and is injured in the process. During the voyage we see the landscape evolve around him, showing how it is altered due to climate changes and erosion.
In the second snippet Hartdegen visits the society of that time and stays with a relatively primitive tribe.
He starts to develop a relationship with the woman who tends to his injuries, but she is seized along with several other tribe members by monster-like humans that come up from underground and hunt them down.
In the third segment, while trying to rescue his new friend, Hartdegen meets a yet different being that tells him how the human species evolved into three sub-species, one of which controls the minds of the others and uses the primitive subspecies that Hartdegen first met as a herd of cattle to be harvested by the monster-like creatures.
The first of the issues on evolution that will be addressed in this lesson plan is the timescale of species change.
Human evolution is commonly understood as beginning 2. The distribution of a trait throughout a population of a particular species has usually also required extremely long timescales, but there are several interesting instances of distinct evolution having been observed in the time lapse of short-term scientific observations.
One of the quickest evolutions on record is the case of the Tropical Blue Moon Butterfly. Click here for a picture to show to the class. Due to a mutation, the genetic information of the butterfly started to include a gene that allowed the butterflies to produce an anti-bacterial chemical or somehow keep the bacteria in check.
This led to a larger proportion of males carrying this gene and a rapid spread of the gene in successive generations of butterflies.
The male population is now back to almost half of all specimens. There are also observations indicating that there has been a noticeable change in the size of adult fish due to man-induced selection. Regulations limit the size of the fish that may be caught. Smaller fish must be left in the sea or thrown back, which allows smaller adults an opportunity to breed.
It is considered a possibility that the catching of the larger fish of highly consumed species is inducing an evolutionary pattern towards a smaller adult size. See Human-induced evolution caused by unnatural selection through harvest of wild animals Fred W. Allendorf and Jeffrey J.
Some call this "unnatural", human-induced selection. Most mutations do not result in changes that are beneficial to the individual and the individual dies before birth, leading to a miscarriage, or if it lives, it will not have offspring and the mutation will die out.
If the advantage is great enough, over what is usually a long period of time, most members of the species will come to have that mutation. Strictly speaking it cannot be said that a particular species has "developed" a new feature. Rather, the competition for survival has selected those individuals that are more fit through a process called natural selection.
Since the environment is always changing, what is beneficial is always changing as well. An interesting example of the interplay between environment and natural selection has been the recent acquisition by human beings of the ability of adults to digest milk.
In most animals, and in all human beings who lived more than 9, years ago, the ability to digest milk was for the young. It switched off in adulthood.
In early hunter, gatherer societies, the only milk an individual would need would be the breast milk provided by the mother.Technical Notes: Superconductivity also seems to be an example of a process that runs forever.
Most physics textbooks explain that superconductivity is not perpetual motion because it is not a classical effect.
