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

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

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

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

IMPROBABLE BUT COMPREHENSIVE. "At first sight, this may seem a highly improbable thesis, but it provides a tenable explanation of the facts." 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

INFERENCES. "My own hypothesis of the transfer of larval forms depends on genetic mechanisms that are imperfectly understood but that can be inferred." Just as Darwin's work operated in the absence of modern genetics. 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

BINGO. "I introduce the idea of horizontal larval transfer." Ouch. Clunky. But possibly, tantalizingly, fascinating. 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

MODERN ENDOSYMBIONTS. "Many protozoan and metazoan cells harbor vertically inherited endosymbionts in their cytoplasm. Comprehensive reviews have covered most aspects of these ancient mutualistic relationships, including metabolism, genetics, and evolutionary history of the endosymbiont/host cell associations." https://lnkd.in/dHQJqnW View in LinkedIn

HYBRID PHOBIA. "The view that hybridisation threatens the genetic purity of parental species and is a violation of species integrity is pervasive throughout conservation literature. Furthermore, hybridisation is often considered to be an evolutionary dead end because genetic incompatibilities and combinations make hybrids unfit, sterile or absent." https://lnkd.in/dfcW_XQ View in LinkedIn

"INHERITED CHIMERISM is an alternative to the problematic practice of conjuring up additional, gene-donating symbionts at organelle origins to explain gene trees. It places no constraints on the collections of genes that the plastid and the mitochondrial symbionts possessed, other than that it needs to be a genome-sized collection, not tens of thousands of genes, and it allows freely for lateral gene transfer among prokaryotes before the endosymbionts become organelles and afterward. Lateral gene transfers among prokaryotes has received much attention in the past decades. Inherited chimerism incorporates lateral gene transfers among prokaryotes into endosymbiotic theory." https://lnkd.in/d4YBVjh View in LinkedIn
