CONTINGENT IRREVERSIBILITY EXAMPLE 3. "Worker bees may lay male eggs, but cannot establish a new colony on their own." https://lnkd.in/eZ5-m7K View in LinkedIn

POWER OF GRAMMAR. "The emergence of human language with a universal grammar and unlimited semantic representation. Grammar enables a speaker with a finite vocabulary to convey an indefinitely large number of meanings, just as the genetic code enables DNA to specify an indefinitely large number of proteins." https://lnkd.in/eZ5-m7K View in LinkedIn

CONDITIONS FOR COOPERATION. "If cooperation is to evolve, non-additive or synergistic, fitness interactions are needed...but the dangers of intragenomic conflict remain: both relatedness and synergistic fitness interactions are likely to be needed." https://lnkd.in/eZ5-m7K View in LinkedIn

THE DIVISION OF LABOUR EXAMPLES. "Hermaphrodites are replaced by separate sexes: the most convincing explanation for why some organisms are hermaphrodite and some dioecious is in terms of an advantage of a division of labour." https://lnkd.in/eZ5-m7K View in LinkedIn

THE DIVISION OF LABOUR EXAMPLES. "In sexual populations isogamy has repeatedly evolved to anisogamy, with differentiated sperm and ova." https://lnkd.in/eZ5-m7K View in LinkedIn

THE DIVISION OF LABOUR EXAMPLES. "In prokaryotes there is a single cell compartment, whereas in eukaryotes the genetic nucleus and metabolic cytoplasm are separated, and additional organelles have evolved, some recruited symbiotically." https://lnkd.in/eZ5-m7K View in LinkedIn

THE DIVISION OF LABOUR EXAMPLES. "In the RNA world, RNA served as both genetic material and catalyst: today, DNA is the genetic material, and most enzymes are proteins." https://lnkd.in/eZ5-m7K View in LinkedIn

THE DIVISION OF LABOUR EXAMPLES. "The evolution of many specific enzymes from a set of multifunctional, low-efficiency enzymes. If the first protocells were equipped with a few multifunctional enzymes, more efficient enzymes could evolve only by duplication and divergence." https://lnkd.in/eZ5-m7K View in LinkedIn

THE DIVISION OF LABOUR EXAMPLES. "In Pleodorina, there is a partial division of labour: some cells start with vegetative functions, but later differentiate into gonidia (asexual propagules)." https://lnkd.in/eZ5-m7K View in LinkedIn

THE DIVISION OF LABOUR EXAMPLES. "The specific name, Volvox weissmania is a reminder that these algae are an excellent example of the segregation of the germ line and soma. Most members of the order possess only a single cell type, which fulfills all vegetative and reproductive functions." https://lnkd.in/eZ5-m7K View in LinkedIn
