Instructions: Choose Either An Organism That Has Reces
Instructions You Can Choose Either An Organism That Has Recently Become
You can choose either an organism that has recently become extinct or one that has recently been described. Using a short PowerPoint (4–7 slides), describe that organism to your classmates. Explain why the organism might have gone extinct or why the new organism has recently been described. Be sure to include a description of the organism, its habitat, the environmental pressures on your organism, and a final interesting story or fact about your organism. By 04/17, your PowerPoint should be posted by the third day of the discussion opening to allow time for interaction. Your initial post should be between 75–100 words.
Paper For Above instruction
The assignment requires selecting either an organism that recently went extinct or one that has been newly described. The goal is to create a concise and informative PowerPoint presentation consisting of 4 to 7 slides that introduces the organism to classmates. The presentation should include several key aspects: a clear description of the organism, its natural habitat, the environmental pressures that contributed to its extinction or led to its recent discovery, and a compelling or interesting fact related to the organism. These components will provide a comprehensive understanding of the organism's recent history or discovery.
In preparing the presentation, it is important to consider the ecological and environmental context that influences these organisms. For extinct species, factors such as habitat loss, climate change, human activity, or invasive species often play a role and should be explained. Conversely, for newly described species, details about the discovery process and why it remained unknown until now are relevant. Including a final interesting story or fact about the organism can engage classmates and highlight its uniqueness.
The assignment submission deadline is April 17, with the PowerPoint posted by the third day of the discussion to facilitate peer interaction. The initial post should be concise, between 75 and 100 words, summarizing the key points of the presentation. Such brevity ensures clarity and encourages further discussion.
This activity emphasizes understanding ecological and evolutionary dynamics through recent biological discoveries or extinctions. It integrates research skills with communication, fostering awareness of biodiversity changes. By analyzing why an organism has recently become extinct or newly described, students gain insights into the ongoing impacts of environmental change and scientific exploration. Overall, this exercise aims to develop concise scientific communication and deepen understanding of biodiversity and conservation issues.
