The Science Problem of the Week will be kept on line for not less than 1 week. After 12 problems have been posted, the person with the most correct answers will win a fabulous prize! Last Round's Winners: Dominic Rankin The 26th round of the Science Question of the Week Competition was won by Dominic Rankin, who correctly answered 12 out of 12 questions! Congratulations, Dominic! Now, on to the current competition. The prize for this round is the winner's choice of the following:
Please note that you are allowed to do research to find the answer to this question, but you CANNOT post the question in a public forum in order to get the answer. This is the TWELFTH AND FINAL problem that goes towards this prize. Zoologist Dr. John Grehan and physical anthropologist Jeffrey Schwartz have been promoting the idea that the closest evolutionary ancestor to human beings is the orangutan. Their most recent paper (published in the June 18th edition of the Journal of Biogeography) makes a very strong case that the apes most similar to humans are the orangutans. Question: This proposition is causing a major storm in evolutionary circles. Why? This question will be replaced on or about July 9th.If you can answer this question, please use the reply form below. Once again, the Science Question of the Week is for students of age 13 - 18 years. Your E-MAIL address must be supplied in the reply form below, or your answer will not count! Note: Compliance with the Children's Online Privacy Protection Rule prevents us from accepting entries from children under the age of thirteen. By pressing GO you acknowledge that you are age thirteen or older. We are sorry for this restriction. Last Week's Question: In modern crime-solving, DNA evidence is very important. If scientists can match something like a hair or some blood from a crime scene to your DNA, you have a lot of explaining to do! However, DNA evidence is not perfect. For example, DNA evidence cannot distinguish between identical twins. Thus, a DNA match is not necessarily unique to an individual. Question: Is there any other identifier in criminal science that is more individual than DNA? In other words, can crime-solvers find something at a crime scene that is totally unique to an individual so that it can even distinguish between identical twins? Answer: Fingerprints are a more unique identifier than DNA. While identical twins can have the same DNA, they cannot have the same fingerprints. This is because fingerprints are determined by both DNA and the environment of the fetus during the first 20 weeks of its development. Even though twins develop in the same uterus, they are in different positions, which affects their environment. As a result, they are exposed to slightly different environments, which produces slightly different fingerprints. Last week's question was answered correctly by: Aslan Konsavage, Laura Abell, Jasmine, Melissa Likiardopoulos, Amber N., Ellen Dore, Scott Mokris, Isaac Daudelin, Gabriela Scottaline, Elizabeth Compere, David Daudelin, Daniel Barry, Christa Whitney, Khieya, Natalie Choo, Alexis, Jeremiah Daul, Samantha Thompson, CJ Lues, Elianna Isaac, Jon Dudo, Laura Aumen, Hope Majeres, Michael Koenig, Sarah Bussey, Brittany Church, Jacob Martin, Gavin Donley, Susanna, Matt Kelly, Ryan Peters, Jacob N Jones,Nathan Bates, Mike Weaver, Brianna, David, and Joshua Harm.
