Natural selection is a key part of how evolution works. But it can be tough for species to adapt to changes. Here are some challenges they face:

1. Genetic Variation:

   • If there isn’t enough genetic variety in a population, it’s harder for them to adapt.
   • Sometimes, mutations happen, but they might not happen often enough, or they could be harmful.

2. Environmental Change:

   • When the climate changes quickly, many living things struggle to keep up.
   • Destruction of their homes makes it even tougher for species to survive.

3. Reproductive Constraints:

   • When animals breed within a small group, it can cause genetic problems.
   • This makes the population weaker and less able to handle challenges.

Solutions:

• Working on conservation programs can help increase genetic diversity.
• Creating protected areas can lessen the impact of environmental changes.
• Teaching people about biodiversity can encourage better care for nature and ecosystems.
