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