Molecular Evolution Lab

- There are many mutations that happen naturally within DNA sequences over time. Most are minor, and have little effect upon an organism. However, some mutations actually provide species with useful adaptations that could help them evolve into more efficient species. Some mutations on a catalytic site completely alter the functioning state of a protein.

The reason for doing this lab is to study evolution using small population of finches on two different islands. I used different charts and graphs to find limitations on natural selection. Then find the effect evolution will have on beak and population over a certain time period. Using three different assignments I have to develop different hypothesis comparing and contrasting the average beak size and population size changing rain fall, beak sizes, population and island size on Darwin’s and Wallace experiments.

The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied.

I set the parameters on precipitation to 0, and the island size to .3km. I then ran the experiment for 300 years.

Mutations occur in the DNA sequence of a gene in an organism. When it comes to the importance of mutations, evolution is the

According to the report of the U.S. Department of Health and Human Services National Institute of Health presented in 2005, chimpanzees share 96% of the human gene sequence. It allows to draw a conclusion that humans and chimpanzees are very closely related to each other, and this relation is great than between humans and other species, such as gorillas or orangutans. Regarding evolution of humans, it is also interesting to note that according to taxonomists originally both humans and apes belonged to the same superfamily of primates, but later they were separated into families: humans - to Hominidae, and apes – to Pongidae. (Steffof,

As well as this, certain blood proteins are found in a number of species. When genetic code (DNA and RNA) is used by a cell, it builds amino acids in a sequence, which forms protein. Chemical tests can determine whether one species has the similar blood proteins to another, thus showing evidence of evolutionary relationships. Organisms with a common ancestor have a close number of amino acid sequences in common. For example, chimpanzees and humans have no difference in their amino acid protein count in their haemoglobin – evidence for a common ancestor.

Ever felt oddly connected to the monkey family? Maybe felt like a long lost cousin? Well it's not so odd after all. Recent studies have shown that human and chimp Deoxyribonucleic acid (DNA) is similar because the two species are related. Humans and chimps come from a single ancestor.

Our species all have the same DNA or same genetic code. DNA is kinda of a molecular blueprint for a living thing. Our DNA says that we are bacteria, we are unicellular, so we only have one cell in our body. Our DNA lives in the

Biological Background: It is scientifically proven that DNA (deoxyribonucleic acid) contains genetic material and highly specific to individual. DNA fingerprint can be tested by restriction fragment length polymorphism (RFLP) methods and Polymerase chain reaction (PCR) methods. Although RFLP is considered more accurate, due to the cost and requirement of longer period to complete, it is not commonly used. While only 1% of genetic materials are unique to individual, the short tandem repeats (STR) sequences called minisatellites can be used to distinguish all humans as it shows great variation between each person (What is DNA fingerprint? 2016).

The species Homo sapiens (human) is compared and contrasted to Pan troglodytes (chimpanzees) by the author. He rapidly clarifies, that several broad areas of research, which suggest that chimps are the closest living relatives to humans. Recently, data has ben obtained from DNA hybridization which suggests that humans, chimpanzees, and gorilla (Gorilla gorilla) are all very closely genetically related. Human DNA and chimpanzee DNA only differs by 1.6%. Gorillas differ another 2.3% from both chimps and humans. Also do gorillas carry a strong implication that the chimps and humans branched off from the rest of the primates at the same time through a common ancestor.

The results from the lab is similar to the hypothesis; as the movement of the students increase, the time it takes for BTB to turn yellow decrease. Exerciser 1 started with standing and blowing onto the BTB solution. The average time it took for Exerciser 1 to turn the BTB yellow was 9.04 seconds. Exerciser 1 then walked around the room for a minute. The average time it took Exerciser 1 to turn the BTB yellow after walking for one minute was 5.80 seconds. Exerciser 1 chose the exercise of doing push-ups. The average time it took for Exerciser 1 to turn the BTB yellow was 4.82 seconds. This shows how the more intake of oxygen plus more movement causes the production of carbon dioxide the increase. This is also shown through Exerciser 2 who also

Did you know that you share the same genetics as a mouse, or what about a fruit fly, and also a chimpanzee? In this paper I will be talking about how we share the same genes, and what the percentage is o the same genes we share with the 7 model organisms. I will also be telling important information on why we are related and how this all came to be.

The authors of this paper wanted to focus on choosing to investigate the effect of major histocompatibility complex (MHC) feto-maternal similarity on propagation in a cynomolgus macaque made out of animals of Mauritian plunge. The Mauritian-determined macaque populace presents an extremely limited MHC polymorphism (just seven establishing haplotypes) because of a solid establishing bottleneck effect.
