ABOMINABLE MYSTERY. "The evolution of land plants, especially the sudden appearance of flowering plants, represents one of the great mysteries for evolutionary theory. Indeed, Charles Darwin characterized this sudden origin and rapid evolution of flowering plants as the “abominable mystery”." https://lnkd.in/eDvT22D View in LinkedIn

SALTATIONS. "Many species remain virtually unchanged for millions of years, then suddenly disappear to be replaced by a quite different, but related, form. Moreover, most major groups of animals appear abruptly in the fossil record, fully formed, and with no fossils yet discovered that form a transition from their parent group."" "C.P. Hickman, L.S. Roberts, and F.M. Hickman, Integrated Principles of Zoology, p. 866 (Times Mirror/Moseby College Publishing, 1988, 8th ed). View in LinkedIn

"THE EVOLUTION of seed plants and later angiosperms appears to be the result of two distinct rounds of whole genome duplication events. These occurred at 319 million years ago and 192 million years ago. Another possible whole genome duplication event at 160 million years ago perhaps created the ancestral line that led to all modern flowering plants." https://en.m.wikipedia.org/wiki/Flowering_plant View in LinkedIn

"GENOME DOUBLING occurs when an organism mistakenly gains an extra copy of every one of its genes during the cell division that occurs as part of sexual reproduction. The extra genetic material gives genome doubled organisms the potential to evolve new traits that can provide a competitive advantage." https://lnkd.in/e27U-gk View in LinkedIn

DOMINANT PLANTS. "Our world is an angiosperm world. The roughly 350,000 known species of flowering plants make up about 90% of all living plant species. Without them, we would have none of our major crops including those used to feed livestock, and one of the most important carbon sinks that mop up our carbon dioxide emissions would be missing." https://lnkd.in/e27U-gk View in LinkedIn

SCIENTIFIC REVOLUTIONS. "No one group of observers has a monopoly on truth, and the history of western science makes it quite clear that the scientific truths of today will, in ever-decreasing intervals of time, constitute the bulk of tomorrow's discarded hypotheses and superseded knowledge." https://lnkd.in/dvpgYsT View in LinkedIn
