Rare All-Female Ant Society That Reproduces By Cloning Discovered

Mycocepurus smithii

A group of Amazonian ants have evolved an extremely unusual social system: They are all female and reproduce via cloning. Though their sexual organs have virtually disappeared, they have also gained some extraordinary abilities.

University of Arizona biologist Anna Himler orginally began studying the ants, called Mycocepurus smithii, because they had incredible success as farmers. Many breeds of ant keep domesticated “farms” where they breed various kinds of fungus for nourishment. But Mycocepurus smithii was able to breed fungus far more successfully, and in greater varieties, than other ants Himler had encountered.

As she and her team studied the insects, they realized there were no male ants anywhere to be found. Himler told the BBC that it’s possible the ants evolved so as “not to operate under the usual constraints of sexual reproduction.” Interestingly, the fungi that the ants cultivate also reproduce asexually. But why would these ants choose to emulate the reproductive cycle favored by their crops? Himler explains:
“It avoids the energetic cost of producing males, and doubles the number of reproductive females produced each generation from 50% to 100% of the offspring.”

All the members of the colony are clones of the queen. While that means the queen can control every aspect of the population, it also makes the colony vulnerable to pandemics. A virus that can kill one ant can kill all of them, since they all have the exact same immune systems. On the other hand, it seems that a lack of men gave these women more time and energy to cultivate some of the most elaborate forms of ant agriculture ever studied.

According to Himler, ants often evolve highly unusual reproductive strategies. But all-female ant societies are highly rare.

Stages of Development : Understanding Human psyche

The four stages of psychological development

One of the basic pillars of the study of human psychology is the analysis of the subconscious and conscious mind. Sigmund Freud was one of the first to clearly identify and characterize the ‘areas’ where our psychic energy flows. During the first part of his notable life he stated that these were the ’subconscious’, ‘preconscious’ and ‘conscious’ mind.

If we wanted to get an idea of how each of them is involved in our ideas, feelings, thoughts, decisions and motivation (which are key in our daily and professional lives), we should picture ourselves as an iceberg. The tip of the iceberg, the only part we see from the surface, is the conscious mind. It’s logical, organized, and we can control it, but still small. The vast and voluminous underlying mass is the unconscious mind. It’s disorganized, illogical, irrational, but defining in how we act.

Modern psychology has attempted to classify how good we are at a certain skill by observing how deep it perforates that iceberg. It thus describes four stages of competence an individual can achieve.

The four stages of human development:

Stage 1: Unconscious incompetence
Stage 2: Conscious incompetence
Stage 3: Conscious competence
Stage 4: Unconscious competence

BEYOND THIS U CEASE TO BE HUMAN...
U're a little more,...

Closing thoughts:
So...

"The More u know,... The less u know."
 
U need to be at or beyond stage 4 to comprehend this...
