Editor's Notes
- Emma and Charles were first cousins married for 43 years before Charles passed away. 10 children total, but two died in infancy and another passed away when she was 10 years old
- Example is sloth, believed ancestors are big but now are small
- Determines which descendants survive to pass on their genes Foundation – step by step some beetles are green and some are brown. Since the environment can't support unlimited population growth, not all individuals get to reproduce to their full potential. In this example, green beetles tend to get eaten by birds and survive to reproduce less often than brown beetles do. The surviving brown beetles have brown baby beetles because this trait has a genetic basis. The more advantageous trait, brown coloration, which allows the beetle to have more offspring, becomes more common in the population. If this process continues, eventually, all individuals in the population will be brown.
