Study Notes
Definition of Natural Selection
- A process where organisms better adapted to their environment tend to survive and reproduce more offspring.
- Central mechanism of evolution proposed by Charles Darwin.
Outcome of Natural Selection
- Leads to the gradual adaptation of species to their environments.
- Can result in the emergence of new species (speciation).
- Favors traits that enhance survival and reproductive success, while eliminating less advantageous traits.
Role of Variation in Natural Selection
- Variation within a species is crucial as it provides the raw material for natural selection.
- Traits are inherited and can differ among individuals, which influences fitness and survival.
- Genomic mutations, sexual reproduction, and environmental factors contribute to this variation, determining which traits are favored over generations.
Selección Natural (Spanish Equivalent)
- Proceso por el cual los organismos más adaptados a su entorno tienden a sobrevivir y reproducirse con más descendencia.
Resultado de la Selección Natural (Spanish)
- Conduce a la adaptación gradual de las especies a sus entornos.
- Puede dar lugar a la aparición de nuevas especies.
Papel de la Variación en la Selección Natural (Spanish)
- La variación dentro de una especie es fundamental para la selección natural.
- Las diferencias en rasgos influyen en la aptitud y supervivencia de los individuos.
