Description

Unit 7 brings biology’s most powerful idea to life: natural selection, the driving force behind evolution. In this unit, you’ll explore how life adapts, survives, and diversifies across time—all rooted in Charles Darwin’s groundbreaking theory. Natural selection explains why giraffes have long necks, why bacteria can become antibiotic-resistant, and why the incredible variety of life exists today.We begin with the principles of Darwinian evolution—variation within populations, overproduction of offspring, competition for limited resources, and the survival and reproduction of the best-adapted individuals. You’ll learn how traits that confer even the slightest advantage accumulate in populations, shaping species over generations.This unit also highlights evidence for evolution, from the fossil record and comparative anatomy to molecular biology and biogeography. You’ll see how homologies, DNA sequences, and embryological patterns confirm common ancestry. We also dive into the Hardy-Weinberg equilibrium, a mathematical model that provides a baseline for measuring whether populations are evolving, examining forces such as gene flow, genetic drift, mutation, and non-random mating.More than theory, natural selection has modern implications. You’ll study antibiotic resistance, pesticide resistance, and evolutionary arms races, showing how evolution isn’t just history—it’s happening around us, every day.By the end of Unit 7, you won’t just understand natural selection as an abstract idea. You’ll see it as the fundamental process that links all of biology, from the simplest bacteria to the complexity of human beings. This unit gives you the lens to view life as a constantly adapting, ever-evolving story.IMPORTANT NOTE: Students under the age of 18, parents, caregivers and guardians are required to purchase this course and allow their students to benefit from it!
