10 random takeaways.
1.
Biologically, you’re constantly changing: cells, synapses, even memories shift. Neuroscience shows that identity isn’t a fixed object stored in the brain. Your identity is less a fixed thing and more a maintained pattern and you have some control. What feels like a stable “you” is a maintained pattern: a story you update every day.

Nerve nets and muscle cells
By 555 million years ago, animals start to emerge. The comb jellyfish is likely the first true animal. Originally, we thought simple sponges evolved furst, but genetic analyses changed that.
3.
Chimpanzee IQ is tricky to pin down because IQ tests are designed for humans, but we can estimate their intelligence with the Encephalization Quotient (EQ). A typical chimp has an EQ of around 2.35, translating to a human IQ of 35 to 40. While it’s fun to speculate, it’s important to remember that chimps don’t think like us—they don’t ask questions or reason abstractly.
4.
From History: 66.04 Million years ago (K–Pg extinction)
The last ornithischians remind us that a branch can stay creative for millions of years while still holding onto a few winning designs. Horns, armor, duck bills, and dome heads were not random quirks. They were long-tested evolutionary solutions that helped these dinosaurs thrive right up to the end.

Article summary:
From crows teaching tool use to humans building libraries, cultural transmission allows knowledge to outlive the individual. It is one of evolution’s most powerful amplifiers, letting useful behaviors spread faster than genes alone ever could. Wisdom is understanding that one of the few things you truly control, is what you allow into your worldview.
6.
From History: 240 Million Years Ago
Around 240 million years ago, during the late Triassic period, a crucial evolutionary development unfolded within the lineage that would give rise to mammals. It is believed that the XX/XY sex-determination system emerged in a common ancestor of mammals, possibly within the genus Therapsida, a group of synapsids that exhibited both reptilian and mammalian traits.
7.
Dogs and wolves are both Canis lupus because they can interbreed and produce fertile offspring. Dogs are classified as a subspecies shaped by human selection, not a separate species. This highlights how species definitions rely primarily on reproductive compatibility, with behavior and appearance playing secondary roles.
8.
From History: 185 Million BCE
Placental nutrient transfer (in placentals)
An example of early live birth is the protomammal Kayentatherium, Jurassic period. This cynodont is related to early mammals and its clutch size suggested egg-laying, providing clues about the transition to live birth. The switch to live birth in mammals, including marsupials and placentals, likely evolved once at their common ancestor, suggesting live birth in mammals has a deep evolutionary history.
9.
The Congo river split Bonobos and chimpanzees about 1.5 million years ago. Chimpanzees are stronger, more aggressive, and have lighter skin. Bonobos have darker skin from birth and are thinner and more bipedal.

From History: ~80 Million years ago (+/- 8 million).
Fowl: chickens, turkeys, pheasants, ducks, etc.
Galloanserae is the living bird branch that includes landfowl and waterfowl—in everyday terms, birds such as chickens, turkeys, pheasants, ducks, geese, and swans.
