Genetic evolution is when living things change over time by passing on traits that help them survive and have babies.
Imagine you're playing a game where you build a robot out of blocks. Every time the robot works well, it gets to send its block pieces to make new robots. But if the robot breaks or doesn’t work as well, those block pieces aren't used as much. Over many games, the robots that are best at surviving and having babies become more common, they're like the winners of the game.
How Traits Work
Each robot starts with a mix of blocks from its parent robots. Some block combinations make it easier for the robot to move or resist falling apart. These are like traits. The better traits get passed on more often, just like the best players in a team keep getting chosen for new games.
A Real-Life Robot
Think about dogs, they're like robots that humans have been playing with for a long time. Some dogs run fast, some are good at digging, and others are friendly. The ones with traits that help them survive and make babies get to pass on their block pieces (genes) more often. That's why we see so many different kinds of dogs today, they've all evolved from the same starting point!
Examples
- Flowers that bloom earlier get pollinated first and have more offspring.
