Interactive Timelines

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.
