Brontosaurus doesn't exist, it was always called Apatosaurus
Brontosaurus was reclassified, then resurrected as a valid genus
Bad Air Causes Disease
Miasma theory was replaced by germ theory
Continents Are Fixed in Place
Plate tectonics revolutionized continental drift theory
The Earth Is the Centre of the Universe
Heliocentrism replaced geocentrism in early modern era
Combustion Releases Phlogiston, an Invisible Fire-like Substance
Lavoisier's oxygen theory replaced 100 years of phlogiston doctrine
Diseases Spread Through Bad Air Called Miasma
Germ theory displaced miasma once microscopic organisms were identified
Continents Are Fixed and Do Not Move
Plate tectonics shows continents move due to seafloor spreading
Dinosaurs were slow, lumbering, cold-blooded reptiles
Many were active, relatively fast, and likely warm-blooded or mesothermic
Acquired Traits Are Inherited
Lamarckism was replaced by Mendelian genetics
Nuclear Fusion Achieved at Room Temperature
Cold fusion claims were not independently verified
Personality and Abilities Are Revealed by Skull Bumps
Phrenology was rejected by neuroscience
The Mind Starts as a Completely Blank Slate
Neuroscience revealed innate cognitive structures
Maggots Spontaneously Generate from Decaying Meat
Life does not emerge from inanimate matter, Pasteur and Lister proved it
Disease Results from Imbalance of Four Bodily Humours
Modern pathology replaced humoral theory with cellular and microbial mechanisms
Wolf Packs Are Ruled by an 'Alpha' Who Fought His Way to the Top
Wild packs are families led by the parents; the alpha idea came from captive wolves
Phlogiston Is the Element of Fire
Replaced by oxygen theory and modern combustion chemistry
Light Travels Through the Luminiferous Aether
Special relativity showed aether unnecessary; light is electromagnetic radiation
Life Can Arise Spontaneously from Non-Living Matter
Pasteur and others proved life arises only from life
The Universe Is in a Steady State
Big Bang theory supported by cosmic microwave background radiation
Acquired Characteristics Can Be Inherited
Genetics shows Lamarckism incorrect; epigenetics shows nuance
Dinosaurs lived in swamps because they were too heavy for land
Most dinosaurs thrived on dry land; swamp dwellings were rare
Dinosaurs dragged their tails on the ground
Most dinosaurs held tails elevated and horizontal for balance
Sauropods needed to live in water to support their massive weight
Sauropods were terrestrial; skeletal features show land-based weight support
Living Things Contain a Vital Force
Vitalism was replaced by biochemistry
Embryos Recapitulate Their Evolutionary Ancestry
Recapitulation theory was oversimplified
Peptic Ulcers Are Caused Only by Stress and Spicy Food
Helicobacter pylori bacteria is the primary cause
Heat Is a Fluid Substance Called Caloric
Joule's mechanical equivalence of heat proved heat is energy, not a conserved fluid
Living Matter Contains a Special Vital Force That Chemistry Cannot Explain
Synthetic urea disproved vitalism; organic chemistry emerged as a normal science
Electricity Is a Weightless Fluid That Flows Between Bodies
Electron theory displaced single-fluid models of electricity
The Sun Is a Giant Ball of Fire
There is no burning; it shines by nuclear fusion, which needs no oxygen
Lactic Acid Makes Your Muscles Sore the Day After Exercise
Lactate clears within an hour; next-day soreness is tiny muscle damage
The Appendix Is a Useless Leftover Organ
It appears to be a safe house for good gut bacteria
Evolution Is a Ladder of Progress Toward Higher, Better Beings
Evolution has no goal or direction; it just fits organisms to their environment
Triceratops and Torosaurus are the same dinosaur
Initially synonymized but likely separate, still debated
Dinosaurs were reptiles like modern lizards and snakes
Dinosaurs were a distinct group, modern reptiles are more distantly related
The Bone Wars created widespread dinosaur classification errors that stuck for decades
Marsh and Cope's competition led to hasty descriptions, some later revised
Iguanodon's thumb spike was originally placed on its nose
An early reconstruction error that was eventually corrected
Crystal Palace dinosaur sculptures shaped wrong expectations for 150 years
1854 sculptures perpetuated outdated reconstructions that influenced popular culture
N-Rays Are a New Form of Radiation
N-rays were a false discovery, never replicated
Polywater Is a New Form of Water
Polywater was a contamination artifact
Farming and Plowing Increase Local Rainfall
The 'rain follows the plough' myth was disproven by climate data
A Mother's Experiences During Pregnancy Mark the Fetus
Maternal impression theory lacks biological basis
Acquired Characteristics Become Hereditary
Neo-Lamarckism failed to explain inheritance
Only Type 1 Diabetics Need Insulin
Type 2 diabetes often requires insulin therapy
Previous Mates Influence Offspring
Telegony was disproven by genetics
The Earth Is Continuously Expanding
Expanding earth theory rejected by plate tectonics
Combustion Occurs When Oxygen Combines with a Substance's Fundamental Essence
Modern chemistry explains combustion via exothermic oxidation reactions
