Things Worth Noting
As humanity establishes isolated colonies in space, human evolution could diverge dramatically over 100,000 years. Natural selection in low gravity might favor taller, slimmer bodies with less muscle and bone density, while cosmic radiation could drive adaptations like enhanced DNA repair, darker skin, or better resistance to mutations and cellular aging. Microgravity causes rapid bone […]
The classic riddle “which came first, the chicken or the egg?” is a philosophical paradox about origins and causality, but science clearly answers: the egg came first. Eggs as reproductive structures existed billions of years ago in single-celled organisms and evolved into amniotic eggs around 340 million years ago, allowing land-based development in reptiles and […]
Dinosaur models are often wrong because fossils rarely preserve soft tissues, colors, or full anatomy, forcing scientists and artists to make educated guesses. Early reconstructions relied on limited fossils and comparisons to modern reptiles, leading to errors like dragging tails, upright postures, shrink-wrapped bodies, and missing feathers. New evidence from better fossils, CT scans, biomechanical […]
If an alien gave you just 10 seconds to ask one big question, what would it be? People dream of asking about faster-than-light travel, dark matter, black holes, or the meaning of life, morals, and the universe’s origin. Others want to know how aliens handle population, resources, government, religion, dreams, psychedelics, or superintelligence. Curious minds […]
The “God gene” hypothesis by Dean Hamer suggests human spirituality is partly hereditary, linked to the VMAT2 gene, which affects monoamine levels in the brain, potentially providing an evolutionary advantage through optimism. Critics argue spirituality’s complexity beyond genetics, involving cultural and personal factors. Long Version The “God gene” hypothesis, introduced by geneticist Dean Hamer in […]
The size of a star and planet are crucial factors in determining the potential for life to exist on exoplanets. Larger stars and planets may pose challenges, but smaller ones may have stable environments. The size and complexity of alien life are uncertain and depend on various factors, including environmental stability and evolutionary processes. Regardless […]
This article explores the search for the first animal, or the common ancestor of all animals that lived over 600 million years ago. It covers the earliest evidence of life, the first animals, and the rise of multicellular organisms. The search for the first animal remains an exciting and challenging area of scientific research. The […]
The scientific consensus is that humans evolved on Earth over millions of years through a process of natural selection. Our earliest ancestors diverged from other primates around 6-7 million years ago, and over time, evolved into the modern human species we are today, Homo sapiens. As to the purpose or reason for our existence, that […]
