Natural selection is important for how new species come to be, but it can be pretty complicated.

Difficulties Faced:

1. Changes in the Environment:

   • When the climate changes quickly, it might be faster than animals and plants can adapt. This can lead to extinction instead of creating new species.

2. Limited Genetic Diversity:

   • If a group of animals or plants is very small, there won’t be much variety in their genes. This makes it harder for good traits to appear that could help them survive.

3. Interbreeding:

   • Sometimes, different species can mate and produce hybrids. This makes it tricky to figure out what a new species really is.

Possible Solutions:

1. Conservation Efforts:

   • Protecting natural habitats can help keep a variety of genes, making species stronger and more adaptable.

2. Research and Monitoring:

   • Scientists can keep studying species to understand how they adapt. This information can help in making better plans to protect them.

In conclusion, natural selection can help create new species, but we need to solve these challenges for it to work well.
