well in case of evolution Darwin's view was plain which i can summarize as
- More offspring's are produced than can survive
- Individuals are variable (morphology, cold tolerance etc)
- Some variability is heritable
- Acquired characters like someone who lost his leg is not inherited by next generation
- of-course the most obvious one- Resources are limited (food,water,cover,breeding opportunities)
-and best adapted traits are more likely to survive- that is successful trait passed on to next generation
