Continuing Evolution in AP Biology Full Explanation

Leave a Comment / AP Biology /

What is Continuing Evolution? Continuing evolution refers to the ongoing process of genetic changes within populations over time due to natural selection, genetic drift, mutations, and gene flow. While evolution has shaped life for billions of years, it is still occurring today. In AP Biology, understanding this concept is crucial for explaining biodiversity, species adaptation, […]

Artificial Selection in AP Biology Full Explanation

Leave a Comment / AP Biology /

Artificial Selection in AP Biology Artificial selection is a vital concept in AP Biology that highlights human influence on the evolution of species. Unlike natural selection, where environmental pressures shape traits, artificial selection involves humans selectively breeding organisms for desired characteristics. This process has led to the diversity of crops, livestock, and even pets that

Fitness in AP Biology: A Comprehensive Guide to Evolutionary Success and Genetic Adaptation

Leave a Comment / AP Biology /

In the world of AP Biology, few concepts are as central to understanding evolution as fitness. But what exactly does “fitness” mean in a biological context? It’s not about how many push-ups an organism can do or how fast it can run—it’s about survival and reproduction. Fitness is a measure of an organism’s ability to pass
