George C. Williams used lottery tickets as an analogy in one explanation for the widespread use of sexual reproduction. [36]

This process is known as a rotational birth, and while it is not a process unique to humans, humans are unique in that nearly all human babies undergo this process out of necessity. A primary hypothesis for why this process and others occur, causing human births to be drastically more difficult than other mammals is known as the obstetrical ...
This fall, learn about different types of pumpkins including heirloom varieties like Jarrahdale and Cinderella. They come in all shapes, sizes, and colors!
The evolution of biological complexity is one important outcome of the process of evolution. [1] Evolution has produced some remarkably complex organisms – although the actual level of complexity is very hard to define or measure accurately in biology, with properties such as gene content, the number of cell types or morphology all proposed as possible metrics.
