Document Summary

According to douglas adams, science has undergone four milestones of science that can be called the four ages of sand , corresponding with glass. The first age is the invention of the telescope (1608) which allowed us to look farther into space, learn about planetary motion and the laws of physics, etc. The second age is the one of the microscope (1678) where humanity was allowed to look closer at things and to analyze smaller things, therefore the start of biology. The third is the computer chip (1961) which allowed us to look more closely in detail and to allow us to compute much more complex things (such as the genome). Last/fourth is fibre optics (1980s) which allowed us to communicate all of this information and to bring experts together. It"s the system that linnaeus created to name animals, using two latin names. The first stands for the genus, the second specifies species.

Question 1

Evolutionary algorithms are used:

In engineering, to arrive at solutions by going through many permutations of possible solutions and allowing them to evolve.

A genetic feature of complex organisms.

A process undergone by the human brain, which is similar to evolution by natural selection.

Another term used for a computer algorithm in general.

Question 2

Human literature and languages can be studied using methods similar to those used for constructing phylogenies because:

There is no other way of studying these things.

Languages evolve roughly along the lines of species, with mutations (changes in words and pronunciation), descent with modification (languages becoming more different along the way), and branching of languages (languages giving rise to other languages that are similar to them).

Because literature and languages are constructed by organisms (human beings), so what applies to one must apply to the other.

Languages undergo a process of word swapping, which is analogous to horizontal gene transfer.

Question 3

The degree to which horizontal gene transfer occurs in eukaryotes is:

Something upon which the entire validity of evolutionary biology hinges.

A mystery that may or may not disprove evolution, but we simply don't know enough about it at this point.

Something that would overthrow the notion that this phenomenon is important in bacteria.

An interesting and potentially important aspect of biology with relevance for how evolution occurs, but not something that would call it into question one way or the other.

Question 4

Learning about the history of scientific theories and the reasons for why they are initially accepted or rejected is important mostly because:

It makes for exciting story telling, and this is very much needed to get people interested in science.

It teaches us about the process of science as it actually occurs, which is somewhat different to the idealized notion of a purely objective undertaking.

It tells us which theories are definitely true or false.

It tells us that science is actually a totally subjective process that tries to present itself as objective. In reality, personal subjective factors are the only relevant factors that really matter in science.

1. Human Impact/Conservation

Okay...youâve (hopefully) learned a lot about biology this semester. We have gone

from atoms, molecules, and cells through organisms and homeostasis, to populations,

communities, and ecosystems. Whew! Even though we started small, we still addressed

larger topics early on. Conversely, now that we have ended our intellectual journey with

ecosystems, we have circled back to talk about elements and molecules and cells. Over

the last couple of lectures, we have talked about human impact and conservation issues

that are challenging the global community.

1a. Of the human impact issues we talked about in class over the last week or two,

take one of them further.

â¢ Clearly identify the issue you will be focusing on, and explain why

it is an important issue to address.

â¢ Explain the biological principles addressed with this kind of

human impact.

â¢ Examine what the natural order of things would be like without

humans being a part of the picture

â¢ Next, re-insert humans into the picture. Identify the normal

biological properties that are impacted by this human activity,

and explain the impact disruption.

the issue would be deforestation.

In your answer, be sure to use specific biological examples and facts from your

notes and text. Use your new-found knowledge by applying it to show the

scientific basis behind one of the environmental crises our planet faces.

1b. Okay, now that the problem is identified and the nature of the disturbance is

explained, letâs talk solutions.

â¢ How would you resolve this issue? What kind of societal things

can you install to bring about solution? Be practical in your

response. Identify stakeholders in the problem/solution, and the

(sometimes) competing interests

â¢ Using what you know from this course (your notes and text),

explain how your above solution(s) resolve the underlying

biological problem(s).

In your answer, be sure to use specific biological examples and facts from your

notes and text. Use your new-found knowledge by applying it to show the

scientific basis behind a solution to one of the environmental crises our planet

faces.

NOTE: This lab assignment has questions related to binomial nomenclature. Please note that the assessment system does not accept formatted text, so you will need to indicate any italicized words by adding âITâ in parentheses after each word that is to be written in italics, (IT). For example, the common fruit fly is genus Drosphila and species melanogaster. When written, it is Drosophila melanogaster. From this example, the correct way to represent the italicized words is by typing, Drosphila (IT) melanogaster (IT).

Record the classes for each of the following arthropods, as determined from the dichotomous key (16 points): Organism 1 (Spider) Organism 2 (Bee) Organism 3 (Beetle) Organism 4 (Blue crab) Organism 5 (Crayfish) Organism 6 (Tick) Organism 7 (Fiddler crab) Organism 8 (Centipede) Organism 9 (Shrimp) Organism 10 (Millipede) Organism 11 (Wasp) Organism 12 (Grasshopper) Organism 13 (Horseshoe Crab) Organism 14 (Mole Crab) Organism 15 (Scorpion) Organism 16 (Squilla) Provide the family name for each shark based on the use of the dichotomous key provided (14 points): Shark 1 Shark 2 Shark 3 Shark 4 Shark 5 Shark 6 Shark 7 Shark 8 Shark 9 Shark 10 Shark 11 Shark 12 Shark 13 Shark 14 Submit the dichotomous key for the "imaginary" animals. (10 points) When might a prepared key be used to identify biological organisms? (5 points) Why are there only two choices for each step in the dichotomous key? (3 points) Why are observation skills important when working with dichotomous keys? (5 points) List the domain, kingdom, phylum, subphylum, class, order, family, genus, and species of humans. (9 points) domain kingdom phylum subphylum class order family genus species What is the scientific name for humans? (4 points) It is estimated that there are more than 1 million species of insects on this planet. Based on this and information gained from this laboratory, what phylum most likely comprises over 90% of the Earth's species? Briefly justify your answer. (4 points) Scorpions and spiders both belong to the same class called Arachnida. Birds and fish both belong to the phylum Chordata. Which two organisms are more closely related? Explain why. (5 points) Using the evolutionary distances from the protein sequences activity (Step 4 of the procedures), fill in the diagram below. The letters should correspond with the sequence numbers (e.g., 1, 2, 3, 4, or 5). (5 points) A B C D E
