A recent article published in the open access journal ZooKeys (1) shows that the 10 Km wide asteroid that impacted the Earth, 65 million years ago – famous for removing the dominant species at that time, nearly terminated the weaklings, the mammals, as well. The paper portrays a picture that is striking – the placental mammals that dominate the world today – from mice to women – just got lucky. They do not seem to posses any significant advantages but the conditions afforded by the trauma, removed all competition, allowing them to thrive.
If mammals were any wiser, they would analyze this event in depth. Dinosaurs had technology – largely supported by biology but the discontinuity made the status-quo technology, a liability. Humans, apparently, on top of the food chain today, seem to be proud of their technology as well – most of which are finely tuned to current conditions. Their societies seem to have morphed into systems with little networked flexibility. Any minor perturbation could send them galloping back 50,000 years – hunting for food and sex, aided by a volatile organ, an evolutionary mishap, on their shoulders. Technology would not matter in such a discontinuity.
10 Km wide space debris are like pebbles in a system, teaming with primordial matter, sprinkled across an irrelevant planetary system at the boundaries of a less than ordinary galaxy, in a bubble universe, member of an infinite multiverse. Such an event is a near certainty for a planet that is in a straight jacket in limited space-time.
