Anatomy of Sims

Anatomy is a branch of biology and medicine that is the consideration of the structure of living things. This page is for the study of the anatomy of Sims.

Sims
Sims are a bipedal, humanoid species, found in SimNation. Most Sims are omnivores, however certain Sims exhibit hematophagy and vegetarianism. Sims have four limbs, two arms and two legs. It is unclear how intelligent Sims are; although they have the ability to use tools and create works of technology, they lack direction and often require a guiding hand, that of the player, to manage some of the simplest of tasks. Sims tend to be social creatures, and can hallucinate if left alone for too long.

Organs
Sims are based on humans, so its safe to believe their organs are similar. Zombies will often think about brains, proving that Sims have brains. Additional proof is provided when the small text displayed when a Sim receives the certificate for achieving level 10 in logic in The Sims 3. They urinate the same way as humans, and their bladders are filled when food is eaten. This shows that Sims have a digestive system. We can assume that Sims have lungs (or a similar organ) due to the fact that in The Sims 3, Sims can hold a contest on who can hold their breath the longest underwater, and Sims WooHooing in a hot tub will come up for air.

Sims' skins are proven to be sensitive to the sun. Sims also seem to have an immune system, as they are able to cure some diseases by simply resting, though some diseases are more serious and can result in death. Vampirism is a unique life state which acts as a virus, which Sims can easily be cured of. Their blood is called plasma and has classes such as O-positive, much like human blood. Dominant and recessive genes also exist in Sim DNA. Also, in The Sims 3, if Sims dye their hair, it will affect their genetics. If a Sim changes their hair color before a Try For Baby, the baby's hair color will either be that color or their other parent's color. If a female Sim changes her hair color while pregnant, the baby's hair color will not be changed. It seems that they can survive without any kidneys, relating to an opportunity in The Sims 3, which is nearly impossible in reality without dialysis.

An interesting thing to note is that Sims digestive systems can break down food completely into liquid waste, meaning that they have a more advanced intestinal tract than humans. And considering the fact that Sims can survive without both kidneys means that the digestive system works double time.

Evolution
One of the biggest differences between Sims and humans is the pace of evolution. Where a human could take millions of years to obtain characteristics which would differ from today's humans, Sims could take less than 25 (in-game) years. One of the most notable examples of Sim evolution could be aging. In The Sims 3, a full life cycle is present. However, in The Sims, almost the entire aging cycle was undeveloped, but 25 years later, in The Sims 2, the system is restored. In The Sims 3, moodlets, traits, wishes, and their lifetime wish make up how they live their lives. In The Sims, characteristics of Sims include a Sim's needs, which affect their mood; personality, Zodiac signs, interests, and age, which affect the interactions a Sim can perform; and relationships, employment, education, and skills, which determine how well Sims perform certain tasks. Most of the characteristics they had 25 years ago were lost. In The Sims 2, Sims have developed wants and fears, aspirations, hobbies and turn ons/offs.
