Charles Darwin had a big idea called natural selection. But this idea has some challenges that make it tricky to understand. Here are some of those challenges:
Not Easy to See: Natural selection happens over a long time. This makes it hard to find clear evidence of it happening.
Traits are Complicated: Many traits, like eye color or height, are controlled by more than one gene. This makes it tougher to see how they change over time.
Fossils are Missing Pieces: Sometimes, the fossil records are not complete. This makes it hard for scientists to follow how different species have evolved.
To help with these challenges, scientists use cool technologies. For example, they use genetic sequencing, which helps them look closely at genes. They also use computer models to get a better understanding of how evolution works.
