☘ Selection
Since aren't enough resources for everyone,individuals have to compete. Those with certain adaptations and advantegous traits are "selected" by nature to survive and reproduce.

🥑Darwin´s homework
Organisms pass traits on: We share our DNA with our family,especially with our parents and some animals,as well monkeys. So,our parents pass traits for us. As also,we will pass our traits for our children,if we have.
Organisms acquire traits: We aquire traits from our parents. We share our DNA with them. Ex: if your mother has green eyes and your father black hair,you probably gonna have green eyes and black hair.
Earth changes over time: The earth is changing. The environment is changing. So the organism who have certain characteristics that help them to adapt to this changes,can reproduce more sucessfully
Strugle for survival: We don't have enough resources for everyone,so we have to compete. That's why some organims are "selected" by nature to survive and reproduce.As the human population is growing,for example in some year probably we can have war because of resources.
🌵 Genetic variation
Genetic variation arrive from mutations,that are changes on the hereditary material. of the organism.They can be beneficial,neutral(have no harm) or harmful depending on the organims and it's environment.
Mutations are a big source of genetic variation. When mutations provid survival advantages to an organism they are passed to the next generation.

🥦Adaptation
Finally,organisms that survive and reproduce,those characteristics help them to adapt to the enronment. Overtime,those characteristics became more common on the population
