Interactive Timelines

Completion requirements
Opened: Tuesday, 20 May 2025, 12:00 AM
Due: Tuesday, 27 May 2025, 12:00 AM

Instructions:

  1. Tool Selection:
    Use an interactive timeline creation tool such as Timeplot, Timeline JS, or any other visual timeline software.

  2. Create Two Timelines:
    a. Population Genetics Timeline:

    • Plot key events/concepts related to Hardy-Weinberg equilibrium and genetic drift.

    • Include real-world examples or experiments that show shifts in allele frequencies over generations.

    • Highlight factors that disrupt Hardy-Weinberg equilibrium: mutation, migration, selection, genetic drift, non-random mating.

    b. Human Population Genetics Timeline:

    • Focus on traits such as lactose tolerance and sickle cell allele.

    • Plot how these traits emerged and spread due to environmental and evolutionary pressures (e.g., agriculture for lactose tolerance, malaria for sickle cell).

    • Annotate significant discoveries, population studies, or adaptation events.

  3. Integration and Reflection:

    • Write a short paragraph (150–200 words) summarizing how evolutionary mechanisms explain the presence and distribution of these genetic traits in modern populations.

    • Reflect on how understanding genetic history helps predict future changes in population genetics.
