1236636968 | natural causality | all events can be traced to natural causes that are potentially within our ability to comprehend | 32 | |
1236636969 | natural selection | A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits. | 33 | |
