- hey! so today I'll be explaining Darwin's theory on evolution through natural selection
- First, overpopulation
- variation
- overproduction is when a species will produce more offspring's than will survive
- for examples these animals kept producing offspring's but only 1/10 would survive
- overproduction
- Adaption
- next
- competition is what caused by overproduction of a species. if there is so many of a species, the resources can not support them all . therefore, they must compete for them.
- like the rabbit and deer both eat berries and plants, but there is only so much recourses
- natural selection
- competition
- next
- A variation is when there is a variation between a species
- for example, some rabbits now have white fur whereas some have brown
- next
- adaptation is the process of a species changing to be better fitted for survival of their environment
- for awhile the rabbits used to be brown and white. However, since the change of environment and tree color, the black fur rabbits had a better chance of survival, so the bunnies adapted to their surroundings
- next
- animals with better adaptations are more able to blend into their surrounds have a greater chance of surviving because they are less likely to be hunted by a predator
- natural selection, this is the process of survival of the fittest. offspring's whom inherit a better survival trait will then survive and reproduce. Therefore, passing the trait to the offspring's'
- finally
