How to Understand Vegetative and Animate Life in a Way that Prepares You for the Next Stage of Evolution
The first living organisms were primitive cells, known as “prokaryotes.” As with minerals in the inanimate phase, prokaryotes grew more complex.
The vegetative phase in the evolution of life corresponds to Stage Two of the four developmental stages of the primordial desire in creation. The difference between Stage One and Stage Two is that Stage One is passive—receiving what Nature gives it—while Stage Two reacts to it, wishing to give back. Similarly, plants respond to their environment and interact with it. Their product, oxygen, is the gift of the flora to our world and is such a vital element of life that without it, evolution as we know it would not be possible.
In his “Introduction to the Book of Zohar,” Ashlag explains that the vegetative level of the desire to receive, as manifested in plants, exhibits a more intense desire to receive. This is why the structures it creates are more complex and have a more noticeable impact on their environment.
Also, unlike minerals, plants are individual specimens with their own reproduction, feeding, and even migration mechanisms. Yet, like minerals, all plants behave similarly—accurately adhering to the program installed within them by the Creator. They open their petals (if they have them) at the same time in the morning, close them at the same time in the evening, and follow almost exactly the same procedure as do the other specimens in their species.
Thus, compliant with the law of yielding self-interest described in the previous section, cells continued to evolve, producing increasingly intricate and complex structures. At first, they congregated in large colonies of single cells. Then, gradually, they began to realize that they could benefit from ascribing different roles to different groups of cells. Some cells became “hunters,” providing food for the entire colony, other cells became guards, others still became cleaners, and each group contributed its best to the community.
In The Study of the Ten Sefirot, Baal HaSulam provides a detailed examination of the internal structure of the Partzuf we discussed earlier, and explains about such systems as the digestive system, the reproduction system, hands, legs, etc.
However, Baal HaSulam describes all these elements as interactions between desires to bestow and desires to receive. These are not physical objects of any kind, although how they behave serves as a “prototype” for the behavior of similar systems in our world. In Kabbalah, a prototype is called “root” and all its offshoots are called “branches.”
Beyond the obvious advantage of size that colonies have over single cells, returning to the topic of evolution, cells in colonies have another edge over single cells: they can focus on a single task and thus perfect their performance, increasing their contribution to the colony and relying on their fellow cells in the colony to provide for their other needs.
Single cells, on the other hand, had to perform all the necessities of sustenance by themselves. This heightened efficiency meant that colonies spent less energy to produce the same amount of food, warmth, protection and any other necessity. Thus, yielding their self-interests, cells began to differentiate.
