Men are visual creatures while women are more verbal creatures. This reflects differences in terms of brain usage. Men and women are designed to be part of a team, acting as two parts that complement each other.
One way to understand this difference is with a simple example. Say we had people gathered in a large auditorium, composed of representatives who spoke every language of the world. That adds to about 6500 languages or people in the audience.
On the stage, I have placed a number of objects. One-by-one, I hold the objects up and each person in the audience says the word for that object, in their native tongue. We may get up to 6500 different word/sounds for some objects, less for other objects, while some objects may have no words in some tongues.
Although there is great diversity of sounds for each object, the visual experience of the objects is universal. Each person in the audience has to see the same thing to be able to express their word for it. This visual language of colors, textures, shapes, curves, lines, shadows and highlights is a type of natural universal language, common to all. The sounds of the 6500 verbal languages are not universal but is somewhat subjective and arbitrary.
Males, on the average, have more natural ability to read and communicate in the universal language of sight. This gives males many advantages. Men tend to be the predominant pioneers and creators of new things. This is not coincidence and is due to the universal language of sight. Males have less need for prewritten audio text to discover new things. They will use the visual and frontal cortex to process what they see in real time. Men can organize themselves into teams easier since they all see the same thing via the universal language of sight.
Females tend by being more verbal and therefore are more limited to using cultural language as their preferred method of adaptation. Cultural language is not universal and has subjectivity. The result is verbal language can be used to create both fact as well as fiction. Less visual skill, using the universal language, makes females less able to tell fact from fiction. They depend more on emotional cues of the current consensus or on strong opinion of those they respect. Once things are written down, women learn faster, but if it is not written, less skill in the universal language makes it harder to extrapolate on their own. This topic shows women have no clue what will be missing if men were not there. I written it down, so the women have a compass
If men were eliminated, culture would become stagnate and not evolve. The books that are already written would be the extent of knowledge, with further books, derivatives. You would lose the creative edge and spontaneous organization skills that come from using the universal visual language.
