Document Summary

Some living organisms such as bacteria will use an asexual mode of reproduction: one night, while you"re studying hard for a biology test, your dog beings barking at you. You are not sure why she is barking, but then you remember that you haven"t fed her tonight. Your cells have a nucleus that contains genetic material: how are dna, chromosomes, and genes related, genes are segments of dna that direct the formation of a specific characteristic. All of the dna in an organism makes up the chromosomes: dna is the basic building material of genes and chromosomes. A chromosome is a large piece of connected dna that is divided up into many genes. Dna is made up of individual nucleotides (a, t, g, and c): evolution is often described as survival of the fittest . How would a biologist best measure fitness from the perspective of evolution: fitness is best measured by the number of offspring.

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.
