Evolution theories
Darwinism its says that the species changes over time, give rise to new species and they share a common ancestor. and that the strongest survives or the one that adapts to the ecosystem. or else they die.
Caracteristics
-
-
1 Between individuals of the same species there are differentiated characteristic or variations that are inherited.
-
Example
The change in color of a chameleon when it has a prey, or to protect it self.
-
marckismThe species transform because of the enviroment induced modifications of the place where they live.Transmited to their decendendets.and it also says the need creates the organism.
-
Example
The trunk of the elephants was modified by long and difficult times of drought and that helped it access the water, so that little by little its trunk evolved until the specimen that we know today.
-
Neo-Darwinism Are processes are produced by the changes present in the genetic composition of population
Characteristics
Natural selection acts over certain individuals so that they have more possibilities of producing offspring.
Produced in the course of time and leaves as a result a ´population preparated to survive the enviroment.
