Evolution on Land and in Rivers
1:11:31 - 1:18:57 (07:25)
Land and rivers each contain unique species due to the different evolutionary processes that occur. While more evolution has happened on land due to the greater number of smaller species, rivers contain a high percentage of species due to their variation from place to place.

The factories we have on Earth today have much larger scale economies than the factories in our cells, which are marvels but don't achieve many scale economies.
1:11:31 - 1:12:55 (01:24)
Summary
The factories we have on Earth today have much larger scale economies than the factories in our cells, which are marvels but don't achieve many scale economies. It is predicted that our future descendants will possess artificial factories, making the factories today seem small in comparison.

The existence of multiple genders, particularly males and females, is due to stronger selection among males in weeding out genetic mutations.
1:14:05 - 1:15:40 (01:34)
Summary
The existence of multiple genders, particularly males and females, is due to stronger selection among males in weeding out genetic mutations. This is why having multiple genders is more advantageous in terms of reproduction and genetic diversity for a species than having just one gender or being hermaphroditic.

The reason behind more variety of species on land compared to the ocean is due to the availability of small niches that promote speciation.
1:15:40 - 1:16:54 (01:14)
Summary
The reason behind more variety of species on land compared to the ocean is due to the availability of small niches that promote speciation. Rivers contain a significant percentage of land species as they vary from place to place, making it difficult for different species to compete with one another.
