DIVERGENT LINEAGES: "not merely phyletic but phylogenetic (literally, referring to the origin of a new phylum or major taxon)—reveals a history that can be concurrently approached from two directions, as each clade relates to the other and as both depart from their common ancestor, best studied as corresponding divergences of developmental programs." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

ATAVISM. "Whereas the compound atavistic and homologous clues can be seen as revealing historical changes within a single evolutionary lineage, others are best viewed through the prism of divergent lineages." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

OVERLAID STRUCTURES. "In development as in evolution, the basic outline is not always erased, and tantalizing residues or traces of earlier forms often remain visible even in later stages of evolution and development." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

DYNAMIC EVO-DEVO. "Vestiges are not mere curiosities or footnotes. As the above examples show, they, along with many other historical holdovers, reveal the dynamic interplay between evolution and development. More than that, such remnants help us to see the distinction between these related and highly similar yet discrete processes." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

CENTRALITY OF MOSAICISM. "There is no doubt that early embryos resemble each other more closely than do late-stage embryos (von Baer’s Law). This is not surprising given the centrality of mosaicism in evolutionary and developmental change, with a basic framework of ancestral, plesiomorphic features that is later supplanted or overlain by derived apomorphies." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

STASIS NOT CHANGE. "Paedomorphosis, the retention of ‘child-like’ larval or juvenile forms (like the external filamentous gills of aquatic salamanders), is yet another way in which organismal features are retained rather than changed, and another way in which the interactions of phylogeny and ontogeny are reflected in their mutual history." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

HOMOLOGOUS STRUCTURES. "The gubernaculum testis, a narrow band of connective tissue that ‘pulls’ the descending testes down into the scrotum, is homologous to the round ligament that suspends the ovary." https://evolution-outreach.springeropen.com/articles/10.1186/s12052-014-0012-5 View in LinkedIn

EPHEMERAL TULIP VARIANTS. "Clusius already noticed in1585 that "broken", multi-colored plants also slowly degenerated: "any tulip thus changing its original colour is usually ruined afterwards and so wanted only to delight its master's eyes with this variety of colors before dying, as if to bid him a last farewell." Striped flowers tended to deteriorate and finally die. He also noticed that uniformly colored flowers were healthy and lived longer."

COINCIDENT with the passion for horticulture in the Edo Period in Japan, the Europeans, in particular, the Dutch, had an obsession with the tulip. Given the close relationship of the the Dutch East India Company in Japan and its very active diffusion of Lilies and other plants from Japan to Europe, the possibility exists for at least a second line of bilateral horticultural diffusion between Japan and Holland.

VARIANTS ARE POLLINATED DIFFERENTLY. "Populations of the common morning glory in the southeastern US are characterized by a striking diversity of flower color polymorphisms. This diversity is probably a consequence of horticultural escapes from cultivation in the 18th and 19th centuries...some color phenotypes are selected by virtue of their differential attraction to insect pollinators." https://lnkd.in/d2DeZMC View in LinkedIn
