Asilisaurus shows that the bird-line archosaurs were already evolving dinosaur-like bodies before true dinosaurs appeared.

One of the last bird-line archosaurs before true dinosaurs is the Nyasasaurus parringtoni, which lived during the Middle Triassic period, around 243 million years ago. Discovered in Tanzania, Nyasasaurus represents a key transitional form, showcasing features that are both dinosaurian and pre-dinosaurian, highlighting the evolutionary path leading to more well-known dinosaurs of the Late Triassic

Before dinosauromorphs like Asilisaurus, the evolutionary lineage would include earlier archosaurs. One such early archosaur is Marasuchus lilloensis, which lived around 240 million years ago. Marasuchus exhibits several primitive features that are on the evolutionary path towards dinosaurs. Kingdom: Animalia > Phylum: Chordata > Class: Reptilia > Order: Dinosauriformes 30 to 40 cm (12 to

Identity is not one thing. It is a living mosaic made of inherited traits, personal choices, social influences, and life experiences. We are not born with a fully formed essence. We build who we become.
A worldview is the lens through which you see reality, yourself, and other people. It is made of your personal language, religion, and philosophy.
30 Phil, Chapter 7, Heraclitus, Touchstone 17: Impermanence and Flux. Impermanence as Flux is the idea of an ever-changing nature of life and the interconnectedness of all things. It is summed up as: “Everything is in flux.” Like the idea a “river,” everything flows. The only constant is change, and to resist it is to resist

30 Phil, Chapter 6, Buddhism, Touchstone 16: Nondualism-Dualism. Nondualism and dualism help to explore the many variations and nuances within the overarching discussion of our nature, whether we have a soul, what happens to it, etc. Dualism says the mind and the body are distinct entities from each other and from the universe. How they interact

30 Phil, Chapter 6, Buddhism, Touchstone 15: Illusion: Self and Non-self. The Buddhist terms of Atman and Anatman relate to the idea of “Self,” or “Atman,” your eternal soul and the Buddhist doctrine of “Non-Self,” or “Anātman.” To understand non-self, you have to understand the concept of “emptiness,” which refers to the idea that nothing lasts

30 Phil, Chapter 5, Confucius, Touchstone 14: Schemas. A schema is a mental structure we employ to organize and interpret information. We classify things into schemas, which we can then modify by adding or removing elements. Schemas help us simplify life. Once things are categorized as normal or abnormal, we utilize our cognitive processes, such as
The Unknowable Dao reminds us that some of reality may be too deep, too fluid, or too vast to capture fully in words.
30 Phil, Chapter 4, Laozi, Touchstone 11: Yin and Yang. Yin and Yang represents the dualistic nature of reality and the energies that constitute it. It is opposite yet complementary forces striving for dynamic equilibrium, symbolizing balance, harmony, and the interplay of light and dark, active and passive, male and female. This harmony is crucial
30 Phil, Chapter 4, Laozi, Touchstone 10: Authenticity. Ziran is often translates to “of its own.” Living in accordance with Ziran means you embrace naturalness. You welcome the spontaneous aspects of existence. With Ziran, you flow with nature while embracing your true self and innate tendencies, your authentic self. Living in accordance with Ziran is you

30 Phil, Chapter 4, Laozi, Touchstone 9: Wu-wei or “non-action” The term wu-wei is often translated as “non-action.” It is a general concept. It is the idea that the universe has a flow, and it is better to ride that flow than to fight it. Wu-wei is non-action, effortless action, or inaction, but does not mean

Pollen evolved about 350 million years ago, by 130 million years ago, flowers improved pollination by attracting partners like bees.
Around 60 million years ago, the early ancestors of primates began to develop a crucial adaptation: the opposable thumb. This evolutionary milestone marked the beginning of increased dexterity.

Slightly greater range of movement and precision: Around 2 to 3 million years ago, the evolution of the human thumb reached a pivotal point. Early hominins, such as Australopithecus and later Homo habilis, exhibited a thumb that was more similar to that of modern humans. This thumb was capable of a greater range of movement

Likely between 25 and 30 million years ago, the evolution of the apes brought about further refinement of the opposable thumb. This period saw the divergence of the lineages that would lead to modern “lesser” apes like gibbons as well as later “great” apes, including orangutans, gorillas, and chimpanzees. The ape thumb evolved to become
About 2 billion years ago, eukaryotic cells are defined by a membrane-bound nucleus and internal organelles. Their emergence created the structural foundation for complex life.
Although protozoa evolved from eukaryotes about 2 billion years ago, it was 1674 that humanity saw them for the first time. That’s when Antonie van Leeuwenhoek, using his meticulously crafted microscopes, discovered protozoa—the first microscopic observation of single-celled organisms. His detailed observations and descriptions of what he called “animalcules” in a drop of pond water
