Fighting the good cause: meaning, purpose, difference, and choice
Haig, David Addison (Springer Science + Business Media, 2014)Concepts of cause, choice, and information are closely related. A cause is a choice that can be held responsible. It is a difference that makes a difference. Information about past causes and their effects is a valuable ... -
Filial mistletoes: the functional morphology of moss sporophytes
Haig, David Addison (Oxford University Press (OUP), 2012)Background: A moss sporophyte inherits a haploid set of genes from the maternal gametophyte to which it is attached and another haploid set of genes from a paternal gametophyte. Evolutionary conflict is expected between ... -
Fitness Variation Due To Sexual Antagonism and Linkage Disequilibrium
Patten, Manus Michael; Haig, David Addison; Ubeda, Francisco (Wiley-Blackwell, 2010)Extensive fitness variation for sexually antagonistic characters has been detected in nature. However, current population genetic theory suggests that sexual antagonism is unlikely to play a major role in the maintenance ... -
Flt1, pregnancy, and malaria: Evolution of a complex interaction
Karumanchi, Subbian Ananth; Haig, David Addison (Proceedings of the National Academy of Sciences, 2008) -
Frugal fat or munificent muscle: genomic imprinting and metabolism
Haig, David (BioMed Central, 2014)Variation in body composition is a popular obsession. The culturally ‘ideal’ body type is light on fat and heavy on muscle but the human population is collectively laying on fat. A new study finds antagonistic effects of ... -
Games in Tetrads: Segregation, Recombination, and Meiotic Drive
Haig, David Addison (University of Chicago Press, 2010)The two alleles at a heterozygous locus segregate during meiosis, sometimes at meiosis I and sometimes at meiosis II. The timing of segregation is determined by the pattern of crossing‐over between a locus and its attached ... -
Genetic Conflict in Human Pregnancy
Haig, David Addison (University of Chicago Press, 1993)Pregnancy has commonly been viewed as a cooperative interaction between a mother and her fetus. The effects of natural selection on genes expressed in fetuses, however, may be opposed by the effects of natural selection ... -
Genetic dissent and individual compromise
Haig, David Addison (Springer Science + Business Media, 2014)Organisms can be treated as optimizers when there is consensus among their genes about what is best to be done, but genomic consensus is often lacking, especially in interactions among kin because kin share some genes but ... -
Genomic imprinting and the evolutionary psychology of human kinship
Haig, David Addison (Proceedings of the National Academy of Sciences, 2011)Genomic imprinting is predicted to influence behaviors that affect individuals to whom an actor has different degrees of matrilineal and patrilineal kinship (asymmetric kin). Effects of imprinted genes are not predicted ... -
Genomic Imprinting Is Implicated in the Psychology of Music
Mehr, Samuel; Kotler, Jennifer; Howard, Rhea; Haig, David; Krasnow, Max (Center for Open Science, 2017-01-27)Why do people sing to babies? Human infants are relatively altricial and need their parents’ attention to survive. Infant-directed song may constitute a signal of that attention. In Prader-Willi syndrome (PWS), a rare ... -
Genomic vagabonds: Endogenous retroviruses and placental evolution
Haig, David Addison (Wiley-Blackwell, 2013) -
Going retro: Transposable elements, embryonic stem cells, and the mammalian placenta
Haig, David Addison (Wiley-Blackwell, 2015) -
High-Resolution Analysis of Parent-of-Origin Allelic Expression in the Mouse Brain
Gregg, Christopher; Zhang, Jiangwen; Weissbourd, Brandon; Luo, Shujun; Schroth, Gary P.; Haig, David Addison; Dulac, Catherine (American Association for the Advancement of Science (AAAS), 2010)Genomic imprinting results in preferential expression of the paternal or maternal allele of certain genes. We have performed a genome-wide characterization of imprinting in the mouse embryonic and adult brain. This approach ... -
Homologous Versus Antithetic Alternation of Generations and the Origin of Sporophytes
Haig, David Addison (Springer-Verlag, 2008)The late-nineteenth/early-twentieth century debate over homologous versus antithetic alternation of generations is reviewed. Supporters of both theories, at first, used Coleochaete as a model for the origin of land-plant ... -
Huddling: Brown Fat, Genomic Imprinting and the Warm Inner Glow
Haig, David Addison (Elsevier, 2008)Heat generated by huddling animals is a public good with a private cost and thus vulnerable to exploitation, as illustrated by recent work on rabbits and penguins. Effects of imprinted genes on brown adipose tissue suggest ... -
Imprinted green beards: a little less than kin and more than kind
Haig, David Addison (The Royal Society, 2013)RNA is complementary to the DNA sequence from which it is transcribed. Therefore, interactions between DNA and RNA provide a simple mechanism of genetic self-detection within nuclei. Imprinted RNAs could enable alleles of ... -
Interbirth intervals: Intrafamilial, intragenomic and intrasomatic conflict
Haig, David (Oxford University Press, 2014)Background and objectives: Interbirth intervals (IBIs) mediate a trade-off between child number and child survival. Life history theory predicts that the evolutionarily optimal IBI differs for different individuals whose ... -
Intracellular evolution of mitochondrial DNA (mtDNA) and the tragedy of the cytoplasmic commons
Haig, David Addison (Wiley-Blackwell, 2016)Mitochondria exist in large numbers per cell. Therefore, the strength of natural selection on individual mtDNAs for their contribution to cellular fitness is weak whereas the strength of selection in favor of mtDNAs that ... -
Kin Conflict in Seed Development: An Interdependent but Fractious Collective
Haig, David Addison (Annual Reviews, 2013)Seeds are complex structures that unite diploid maternal tissues with filial tissues that may be haploid (gametophyte), diploid (embryo), or triploid (endosperm). Maternal tissues are predicted to favor smaller seeds than ... -
Kinship Asymmetries and the Divided Self
Haig, David Addison (Cambridge University Press, 2008)Imprinted genes are predicted to affect interactions among relatives. Therefore, variant alleles at imprinted loci are promising candidates for playing a causal role in disorders of social behavior. The effects of imprinted ...
