BioInteractive is offering free workshops for high school and undergraduate life and environmental science educators. Elephant tusks are important for obtaining food and water, and essential to male elephants for competing for mates, so there is a strong natural selection for having tusks. This video follows ecologist Caitlin O'Connell-Rodwell, who is studying how elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground. In particular, they often are missing their upper lateral incisorsthe anatomical equivalent of tusks in elephants. Hear how educators are using BioInteractive content in their teaching. Fortunately, another research team was carrying out a collaring project to track matriarch elephants. 255 0 obj <> endobj video until time 1:46 and answer the following questions. In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms. Tuskless mothers, on the other hand, had about an equal proportion of daughters with or without tusks (or, in some cases, with a single tusk). Use evidence-based predictions to explain how a population changes over time due to human impacts. Most African elephants have tusks, but some about 2% to 6% of females and even fewer males never grow them. In this video, biologist Shane Campbell-Staton walks through the steps of collecting DNA samples from elephants in Gorongosa National Park and how he plans to analyze their DNA sequences.For more information and related materials, visit HHMI BioInteractive:https://www.biointeractive.org/classroom-resources/genetics-tusklessness-elephants The frequency of tusklessness, the team found, increased from about 18.5 percent before the war to 50.9 percent after. As poaching in Gorongosa has been stamped out through sustained conservation efforts, the number of baby elephants born tuskless has begun to decrease. This data-driven activity accompanies the video Selection for Tuskless Elephants. Discover tools to help plan lessons and opportunities to support professional learning. More than 30 years later, she finally may have her answer. This study is among the first to show that selective killing of large vertebrates can have a direct impact on evolutionary change, says Fanie Pelletier, an ecologist at the University of Sherbrooke in Quebec, who co-authored a perspective piece in Science about the research. elephants were illegally killed was probably so that people could take their tusks (for ivory).

Some prevent pathogens from entering the body, and some attack pathogens already inside the body. In this article from professor Karen Avery, see how she uses this unassuming model organism to teach concepts in cellular biology and genetics. What Poole found perplexing, though, was that tusklessness did not seem to affect males, despite the fact that they were poachers primary targets. This activity guides students through learning and using key scientific terms, culminating in the creation of a customizable diagram. Typically, though, such studies focus on small creatures that have large population sizes and fast generational turnovers because changes they undergo are easier to observe in real time. Data Points are useful resources that use figures from the primary literature and guided sets of supporting questions. rev-a-shelf 6942-28-11-52; stride rite sandals baby girl; five spice beef noodle soup Scientific Explanation of Evolution by Natural Selection. The immune system responds to pathogens in two main ways: innate and adaptive immune responses. hb```lRB The story of African elephants is a powerful case study of how science can inform conservation. Instead of having sons and daughters at an equal proportion, tuskless mothers gave birth to daughters roughly two thirds of the time.
