THE DIVISION OF LABOUR EXAMPLES. "Caste differentiation in the social insects." https://lnkd.in/eZ5-m7K View in LinkedIn

CENTRAL CONTROL. "If a 'selfish' mutation occurs in a chromosomal gene, a suppressor mutation at any other locus in the genome would be favoured by selection. Hence the rest of the genome may win the contest, not because of any analogue of majority voting, but because of the large number of loci, and hence of possible suppressor mutations, that are available for each selfish mutation." https://lnkd.in/eZ5-m7K View in LinkedIn

CONTINGENT IRREVERSIBILITY EXAMPLE 7. "The reversion from sex to parthenogenesis. Amniote vertebrates, although they may be parthenogens, always require sperm from males of another species to initiate development, perhaps because the sperm provides a centriole." https://lnkd.in/eZ5-m7K View in LinkedIn

ODDITY OF LIFE. The chemist George Whitesides has stated, "How remarkable is life? The answer is: very. Those of us who deal in networks of chemical reactions know of nothing like it’." https://lnkd.in/einZ2Fh View in LinkedIn

CONTINGENT IRREVERSIBILITY EXAMPLE 6. "The reversion from sex to parthenogenesis. Gymnosperms are also never parthenogens, perhaps for a different reason: chloroplasts are transmitted in the pollen." https://lnkd.in/eZ5-m7K View in LinkedIn

INFORMATION IS CENTRAL. "Our excuse for writing an article concerning topics as diverse as the origins of genes, of cells, of language is that all are concerned with the storage and transmission of information." The end of a classic paper. https://lnkd.in/eZ5-m7K View in LinkedIn

CONTINGENT IRREVERSIBILITY EXAMPLE 5. "The reversion from sex to parthenogenesis. Mammals are never parthenogens, probably because, at some loci in some tissues, only the allele inherited from the father is active: hence, in an embryo with no father, some essential gene activities are missing." https://lnkd.in/eZ5-m7K View in LinkedIn

INFORMATION. "Developmental biology can be seen as the study of how information in the genome is translated into adult structure, and evolutionary biology is how the information came to be there in the first place." https://lnkd.in/eZ5-m7K View in LinkedIn
