Hello biology enthusiasts! Today, we're going to chat about how the evolution of domesticated animals and crop plants gives us clues about evolution itself. Fasten your seat belts; we're going on a journey through time!

Selective breeding - the hand of humans in evolution

Selective breeding (aka artificial selection) is like Mother Nature's reality TV show, where humans are the judges. It's been around for thousands of years, and it's how we've created different breeds of animals and types of crop plants.

 

Example: Remember our fluffy friend, your pet cat? Or the sheep that provides us with warm wool and milk? They didn't just pop out of thin air! Humans bred them selectively for various reasons. It's like playing a real-life game of Animal Crossing!

Livestock breeds & their wild cousins

Check out the vast differences between modern livestock and their wild species. It's like comparing Iron Man with Tony Stark. Both are the same underneath, but one is supercharged!

 

Example: Ever seen those egg-laying hens in a farm? They're relatives of the junglefowl from Southern Asia, just turbo-charged with selective breeding. Another cool case is the Belgian Blue cattle, massively different from their ancestors, the now extinct aurochs of Western Asia.
