Question

1. define the process natural selection
2. name the book written by charles darwin
3. how the favorable traits are transmitted through generations?
4. what is artificial selection
5. what are mutations?
6. list two causes responsible for extinction

Explanation:

1. Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce more successfully. It is a key mechanism of evolution.
2. Charles Darwin wrote On the Origin of Species.
3. Favorable traits are transmitted through generations via genes. Genes are passed from parents to offspring during reproduction, and if a trait gives an organism a survival or reproductive advantage, it is more likely to be passed on.
4. Artificial selection is the process by which humans selectively breed plants or animals to promote the occurrence of desirable traits in offspring.
5. Mutations are changes in the DNA sequence. They can be caused by errors in DNA replication, exposure to mutagens (such as radiation or certain chemicals), etc.
6. Two causes of extinction are habitat loss (destruction of the natural environment where a species lives) and over - hunting (humans hunting a species to the point of no return).
