Anthro 1 Poem/Song Hall of Fame, Part 1, Fall 2013 Jillian Itow Microevolution When small things change It's microevolution. With this you can mate. Charles Darwin made Natural selection cool. Survive, the fittest! Gene mutation happens. Hair color, skin tone, and eyes Are all affected. New people came in, Caused variation increase; Gene flow happened. Genetic drift caused Variation to decrease: Bottlenecking killed. Only humans care For assortative mating. "Race" does not exist. Pearl Guerrero Processes of Evolution Kareli Espinoza Evolutionary Processes Evolution is Five processes working to Change alleles through time. Allele frequencies In microevolution Do change over time. Reproductively Fit, natural selection: Those who are, survive. Favorable traits For natural selection, Like Darwin's finches. Mutation is change In DNA; it may be Good, neutral, or grave. Change in DNA, Increases variation: It is mutation. Genes flow, DNA Exchanged, connecting people Variation grows. Genetic drift, change Randomly the alleles in The population. Example, not a Random sample, sampling slip Founder principle. Nonrandom mating, People’s preference, only For some ethnic groups. Daniel Agosto The Tarsier The tarsier, an odd-looking creature, Recognized by its enormous eyes, Is nocturnal, a special feature. It likes eating insects, such as flies. It’s a haplorhine, dry-nosed mammal, Only seen in Southeast Asian islands. Its bat-like ears are quite abnormal. It lives in tree branches, not highlands. It has two grooming claws on each foot. Its eye socket is partially closed. Its tail allows it to stay put, And its size keeps it from being exposed. Its tibia and fibula combined, It’s a shame its population declined. Migrate new alleles Into a population: It is called gene flow. Two examples are: Bottlenecks, founder effects: Here's genetic drift. Non-random mating: Phenotypes are essential, Must be preference. Anthro 1 Poem/Song Hall of Fame, Part 1, Fall 2013 Daniella Andrade Sedimentary Street (To the tune of “Sesame Street”) Death and decay With factors for fossils to stay. We learn about this through taphonomy. Can you tell me how to get, How to get to Sedimentary Street? Volcanic lakes Keepin' the fossils in place. That's how we found Darwinius Isn't it neat? Can you tell me how to get, How to get to Sedimentary Street? Clay and slate, Layers found to equate The time the creature lived With stratigraphy. Can you tell me how to get, How to get to Sedimentary Street? It's a dating technique to find All the layers to organize time With older fossils below All the older be-River way, Lining the bones up straight. Small ones lost But all the rest are neat. Can you tell me how to get , How to get to Sedimentary Street? Justine Tran Protein Synthesis-ville (To the tune of “Margaritaville” by Jimmy Buffet) Ribosome starting, DNA charting. Protein synthesis needs mRNA. First get adenine Match it with thymine; Remember uracil gets in the way. Messenger RNA copies the DNA. Translation then needs to happen next. All of these genes must replicate by all means; Mutations can happen and vex. Then transfer RNA And anticodons stay, Combining all the complimentary bases. This protein creation Is our life’s foundation, Between all the DNA laces. Amino acids connected in peptide bonds, Polypeptide chains are the final result. This is the end and there’s no need to pretend, Synthesis is no form of occult.
