Wasps Favor Large Size for Sex

Size matters when it comes to sex. When in the orchid world it does anyway! The plants rely on wasps for fertilization. Apparently, male wasps are attracted to the largest orchids. Shape of plants also has a role.

Orchids are a replica of female wasps, in shape and scent. Two orchids who had two kinds of wasps enamored with them were observed. The wasps did visited both types of plants but they spent more time "copulating' with their favored orchid.

Scent is offered to male wasps on little black beads. This only attracts males to the flowers. Once there, shape and size of blooms affects whether wasps stay or go. Orchids also benefits from this because plants with larger flowers are fertilized and they produce the next generation of orchids.

MALE WASPS GO FOR SIZE

Society and High Intelligence Go Together

We have large brains due to social interaction.  In early societies culture meant things had to be remembered.  Another important function leading to large brains was tools use, though chimpanzees use tools.  The most intelligent people would inevitably become leaders and have the choice of mates, thus passing on their genes.

Intelligence and brain size are of course interdependent.  Animals such as dolphins and elephants have social structures.  They are also very intelligent.  Higher intelligence appears to be naturally selected for in any species.

Apparently, when society develops intelligence must increase otherwise an individual will be "put upon" by the smarter ones.  There is some evidence that really clever individuals tend to be disruptive to a society.  The naive are certainly at a disadvantage.

A thorn in the side of the above theory is that some highly structured societies are composed of small creatures with tiny brains.  Ants, bees and wasps are in this category.
