I'm very happy with the work, publishing has been arranged…johan-nygren (63)in eusociality • 7 years agoThe companion-species hypothesisHow can genetically prescribed selfless behaviour arise by natural selection, which is seemingly its antithesis?[1] In humans, I have proposed that eusociality could be the result of a…johan-nygren (63)in eusociality • 7 years agoFrom the social brain hypothesis to that of the eusocial brain"The “Machiavellian intelligence” hypothesis (or the “social brain” hypothesis) posits that large brains and distinctive cognitive abilities of humans have evolved via intense social competition in…johan-nygren (63)in anthropology • 7 years agoThe Homo lineage created the savanna, rather than the other way aroundThe coast-line on Danakil where both the Australopithecus and Paranthropus genus speciated, would have been different from the surrounding regions in that it was an open landscape, where the field…johan-nygren (63)in anthropology • 7 years agoIncomplete Lineage Sorting (ILS) from the interbreeding event 6 MaScally et al shows that 30% of the gorilla genome exhibits incomplete lineage sorting with the human genome and chimpanzee genome, with 15% of the gorilla genome being closer to human than to…johan-nygren (63)in anthropology • 7 years agoThe Darwinian origin of the great apes, an island in the Afar region, DanakilThe Galapagos of the Great Apes Iguanas became otters on the Galapagos, finches took on every single bird niche, birds on New Zealand lost their wings, the Kiwi bird became the equivalent of a…johan-nygren (63)in anthropology • 7 years agoEvidence of hybridization at 6Ma, mtDNA transfer from gorillae to human-chimpanzee lineage, seen in ps5 NUMT present in extant gorillas, humans and chimpanzeesMitochondrial DNA is inherited separately from nuclear DNA (the chromosomes. ) Fragments of mitochondrial DNA are known to get inserted into nuclear DNA to form NUMTs, i.e. nuclear pseudogenes of…johan-nygren (63)in anthropology • 7 years agoGene transfer between the gorilla lineage and human lineage 6–4Ma, possible empirical evidenceThe gorilla lineage may be a result of the Ethopian plateau forming, from compression of the contintental crust at the Afar tripple junction, which later by extension formed the Afar rift as well as…johan-nygren (63)in anthropology • 7 years agoSubcutaneous fat in humans and gorillas, correlations at a genetic level ?Gorillas have plenty of subcutaneous fat, where Zihlman et al report 13% and 16% in two female gorilla from a paper in 2000[1], and total body fat up to 44% (Zihlman and McFarland, 2000). The…johan-nygren (63)in anthropology • 7 years agoHypothesis to explain the Pthirus host switch as well as Paranthropus: extant gorillas are descendant from island gorillas, living in the mountains on DanakilOnly coastal animals would leave a fossil record in Afar[1, 2], that is, animals living along the coast on south-western Danakil, and whatever lived up in the mountains would be lost (fossils are…johan-nygren (63)in anthropology • 7 years agoThe "companion-species" hypothesis, a new model for the evolution of eusociality in humansSudmant et al published a paper[1] in 2013 on a genome sequence analysis of the speciation of gorillas, humans and chimpanzees. Their data shows that there was a gene deletion event in the…johan-nygren (63)in anthropology • 7 years agoConclusive evidence of gene transfer from Gorillae to gracile Australopithecines 3 million years agoHere is, I think, conclusive evidence of gene transfer from Gorillae to gracile Australopithecines 3 million years ago. The data that is interpreted as deletions here, is gene transfer from the…johan-nygren (63)in anthropology • 7 years agoEusociality, and the "companion-species" hypothesis of human evolutionI came up with the "companion-species" hypothesis the other day, which builds on a 2012 study published in nature.com that 15% of the human genome is closer to gorilla than chimpanzee, as well…
