Darwin's Four Postulates
Let's explore Darwin's main theories.
2. In every generation, more offspring can produce that can survive. Each generation has more children, therefore there will always be more produce.
3. Survival and reproduction is not random. Some individuals find more mates and survive more. The best and the fittest will survive.
4. Phenotypic variants are passed on to offspring. More fit phenotypes are represented by next generation. This means that all of the individuals attributes are passed on to the next generation.
