"THE WILLIAMSON THEORY offered a radical one-step alternative and the initial experimental confirmation of his theory." Foreword. (Lynn Margulis and Alfred I Tauber). Regardless, journal reviewers branded these ideas as rubbish. https://books.google.es/books?hl=en&lr=&id=4Bv_CAAAQBAJ&oi=fnd&pg=PR3&dq=evolution+of+larval+stage&ots=Ajv40BxpV8&sig=UoAuSNQhyUJxvYurqij18mPF3GM View in LinkedIn

WILLIAMSON HYPOTHESIS. "Already for many cell biologists the theory will not appear so very far-fetched, because the origins of organelles which are cytoplasmically inherited, such as the mitochondria and the chloroplasts, are thought to lie in the fusion of two different taxi to form a single entity. The original association is thought to come about through a symbiotic or parasitic relationship." https://books.google.es/books?hl=en&lr=&id=4Bv_CAAAQBAJ&oi=fnd&pg=PR3&dq=evolution+of+larval+stage&ots=Ajv40BxpV8&sig=UoAuSNQhyUJxvYurqij18mPF3GM View in LinkedIn

WILLIAMSON HYPOTHESIS. "Williamson developed a controversial hypothesis proposing the acquisition of larval stages in some marine organisms by hybridisation between two distant animal species (a speciation process referred to as hybridogenesis by Williamson). The fraction of the genome of one of the contributor species would be restricted to lead the developmental program of a newly acquired larva whereas the genome of the other contributor would drive the development of most of the adult anatomical structures." https://lnkd.in/d_TVjhq View in LinkedIn

CURRENT DOGMA. "The modern emphasis on endosymbiotic explanations for numerous eukaryotic features, including the cell itself (the so-called chimeric hypotheses), can be seen not only as resulting from the advent of molecular and genomic data, but also from the intellectual acceptance of the endosymbiotic origin of mitochondria and plastids." https://lnkd.in/dP2c_bU View in LinkedIn

NEW LATERAL GENE TRANSFERS. "The implied transfers of large amounts of genetic material are attributed to successful hybridizations between animals that are not closely related." https://books.google.es/books?hl=en&lr=&id=4Bv_CAAAQBAJ&oi=fnd&pg=PR3&dq=evolution+of+larval+stage&ots=Ajv40BxpV8&sig=UoAuSNQhyUJxvYurqij18mPF3GM View in LinkedIn

LARVAL TRANSFER. "Rather, it proposes that on occasion, in evolutionary history, larval and embryonic forms that originally evolved in one lineage have later appeared in another, as if they had jumped from one branch of the phylogenetic tree to a distinct, and sometimes distant one.” https://books.google.es/books?hl=en&lr=&id=4Bv_CAAAQBAJ&oi=fnd&pg=PR3&dq=evolution+of+larval+stage&ots=Ajv40BxpV8&sig=UoAuSNQhyUJxvYurqij18mPF3GM View in LinkedIn

HORIZONTAL LARVAE. "My alternative theory, horizontal transfer of larval form, does not postulate that larvae have altered very little or become superficially more similar as their corresponding adults have evolved striking differences." https://books.google.es/books?hl=en&lr=&id=4Bv_CAAAQBAJ&oi=fnd&pg=PR3&dq=evolution+of+larval+stage&ots=Ajv40BxpV8&sig=UoAuSNQhyUJxvYurqij18mPF3GM View in LinkedIn

NOT SUFFICIENT. "Paradoxes exist, however, in the many examples of apparently closely related larvae giving rise to apparently distantly related adults, and the less common examples of apparently distantly related larvae giving rise to apparently closely related adults. Conventional explanations, when they exist, invoke either convergent evolution or larval conservatism." https://books.google.es/books?hl=en&lr=&id=4Bv_CAAAQBAJ&oi=fnd&pg=PR3&dq=evolution+of+larval+stage&ots=Ajv40BxpV8&sig=UoAuSNQhyUJxvYurqij18mPF3GM View in LinkedIn

MOSTLY ADEQUATE. "The larva and adult phases in development commonly follow totally different ways of life, and the process which Darwin called "descent with modification" and natural selection are frequently adequate to explain the differences in form that adapt them to their different environments." https://books.google.es/books?hl=en&lr=&id=4Bv_CAAAQBAJ&oi=fnd&pg=PR3&dq=evolution+of+larval+stage&ots=Ajv40BxpV8&sig=UoAuSNQhyUJxvYurqij18mPF3GM View in LinkedIn
