Homo sapiens sapiens is the "classic" human species, the foundation of all subsequent evolution. Its body and mind are balanced, without extreme specializations: average intelligence, moderate strength, functional senses, and a flexible biology that allows it to adapt to diverse environments. Although it lacks extraordinary enhancements, its creativity, cultural learning, and capacity for cooperation have ensured its survival and dominance of the planet for millennia.

Classic humans (Homo sapiens sapiens) are rather rare, as there aren't as many left as before. Many gather in communities far from the mutant cities, but others remain in the cities for opportunities. Most subspecies are surprised to see a Homo sapiens sapiens, but others take it for granted.

In the vast spectrum of evolved humanity, each subspecies carries with it its own advantages and particularities, but none is entirely free from biological randomness. Despite their adaptations, all subspecies, from Homo fortachon to Homo felix, can be susceptible to external or internal diseases: viruses, bacteria, fungi, or unpredictable genetic mutations can affect any individual, altering their metabolism, musculature, nervous system, or physiological balance. However, there are exceptions: Homo cytarchus, Homo Omega, or Homo Sapiens Plus, with their armored cellular biology; Homo Mentalis (due to their technology); and Homo immunizati, with their outstanding immune system, possess almost total resistance to conventional pathogens and mutations that would affect other subspecies. Similarly, extreme cellular or metabolic enhancements in other evolutionary lineages may partially protect them from certain internal failures or common diseases. Outside these limits, evolution proves capricious: a Homo magnus, a Homo devorans, or even a Homo felix can fall victim to unexpected afflictions, from viral infections to metabolic imbalances, turning the lives of these subspecies into a delicate balance between their extraordinary biology and the inescapable vulnerability that accompanies all living flesh. In other words, evolved subspecies are not omnipotent: biology and disease remain forces that dictate destiny, reminding us that even the most optimized organism is still, in essence, an organism subject to the unpredictable roulette of life with more or less advantage.

Homo cytarchus: Extremely resilient and regenerative cells with armored DNA. Their biology is stable and long-lasting, prioritizing longevity and continuous repair.

Homo ultra Improved version of Homo sapiens plus: combines strength, intelligence, endurance and optimized sensory skills, a body and mind "patched" for maximum performance.

Omega sapiens: A hybrid of Homo ultra and Homo cytarchus, combining advanced physical and cellular optimization. Its biology integrates multiple high-performance systems.

Universal sapiens: Synthesis of almost all subspecies: strength, intelligence, dexterity, vision, balance, immunity and adaptive skills combined in a single organism.

Homo felix: Their biology is centered on emotional stability and happiness, using well-being as a tool for survival and cognitive efficiency.

Human voice: Its vocal apparatus functions as an acoustic modulator, capable of projecting sound, volume, and frequency with extreme precision for long-distance communication and alerting.

Homo mortalis: They look like normal humans, but they carry an internal organ that contains a lethal virus that only becomes active after their death, making their passing a critical biological event for the environment.

Homo cellulosus: Specialized in digesting cellulose, its digestive system and metabolism are adapted to extract energy from fibrous plants that no other human can utilize. Its entire body functions as a highly efficient fermentation system.

Homo fabricator: It can synthesize its own essential vitamins and nutrients, making it independent of diet and highly resistant to nutritional deficiencies. Its metabolism is chemically self-sufficient and regulated.

Homo compresmibilis: It has extremely flexible bones that allow it to bend, compress, and move through spaces impossible for other humans, with highly elastic joints and ligaments.

Homo fortachon: Everything about his body is optimized for brute strength: massive musculature, reinforced tendons, and a bone structure capable of withstanding extreme loads. Physical power is his defining characteristic.

Homo mentalis: Their brains are highly developed, with extraordinary neuronal density that maximizes thought, strategy, and creativity. Cognition is their primary tool for survival and dominance. They are extremely technologically advanced, possessing a cure for almost everything.

Homo armatus: It develops natural armor, whether through thick skin, bony plates, or layers of biological protection. Its survival depends on extreme passive defense.

Homo sexus: Their biology is geared towards efficient and frequent reproduction, with traits that facilitate polygamy and maximum fecundity. Their reproductive strategy defines their existence.

Sagittarius homo: His hands, with 12 fingers, including two thumbs, allow him to manipulate objects with superhuman precision. His manual dexterity is superior and adapted for fine tools and tasks.

Homo immunizati: Their immune system is extraordinarily powerful, capable of resisting almost any pathogen. Their biology prioritizes internal defense over any other function.

Homo devorans: An extreme and adaptable omnivore, capable of consuming meat, vegetables, and decaying matter. Its digestive system tolerates foods that others could not process.

Homo stabilis: Extreme balance in all positions: standing, lying down, on one leg, or in acrobatic postures. Their musculoskeletal and vestibular systems are optimized for absolute stability.

Homo substitubilis: Their body can replace one support with another without losing stability: feet, hands, or limbs interchangeable depending on the posture. Fluid and adaptable mobility.

Homo oculis claris: Perfect vision, resistant to optical illusions. Their visual perception is stable and reliable, capable of maintaining spatial judgment even in deceptive conditions.

Furnus silens: Extremely silent movement and communication. It can move and modulate sounds without generating an acoustic trace, including its own voice.

Homo inversus: It breathes in a "reversed" way: it absorbs carbon dioxide and releases oxygen, a respiratory system that is biologically reversed compared to a normal human.

Machinator soni: Blind, but his hearing is so keen that he perceives the environment with absolute precision, able to use echoes and sounds for navigation and extreme orientation.

Homo polydactylus prensilis: It has 24 functional fingers on its hands and feet, all prehensile and very long, which expands its ability to manipulate and move on complex surfaces.

Homo magnus: Larger than the average human, with bones and muscles reinforced to support his size. His strength and physical presence are amplified by his height and mass.

Homo parvus: Very small, compact, and agile. Optimized for mobility in confined spaces and minimal resource consumption. Maintains functional proportions despite its small size.

Homo nocturnus: Adapted to the night, with extreme vision in the dark and acute sensitivity to light. Its biology is geared towards nocturnal activity and hunting under low-light conditions.
