cladogenesis
geometric form of a tree = pattern of branching of a cladogram.
This can mean a branching nerve cell or a branching mineral. Here are some sentences.A dendrite carries a nerve signal along the body.That rock shows the branching pattern of a dendrite mineral.
A pattern of speciation in which most species in an area appear at the same time
Punctuated Equilibria is a theory proposed by Stephen Jay Gould and Niles Eldredge to explain patterns of speciation in the fossil record. They pointed out that the record seems to show most species undergo long periods of relatively little change (stasis), then undergo rapid bursts of change at irregular (punctuated) intervals. Evolution did not seem to proceed at a stately, constant, slow speed. Gould and Eldredge explained this by taking the standard idea of how species form (allopatric speciation, or speciation in small isolated groups at the periphery of populations) and showing that this process would produce exactly the pattern which is observed in the fossil record. Essentially, evolution and speciation can occur rapidly in small isolated populations, sometimes too quickly for the fossil record to track all of the intermediate forms. The result is what looks like abrupt emergence of forms with little or no transitional stages, when in reality the evolution had occurred through intermediate stages, only too quickly for the slow process of fossilization to capture it.
Amethyst fracture refers to the way amethyst gemstones break or shatter when subjected to external force. It typically exhibits conchoidal fracture, which means it breaks in a smooth, curved manner like the inside of a seashell. This fracture pattern is a characteristic of many minerals and gemstones, including amethyst.

Environmental changes influenced speciation
dendretic drainage pattern ~Hehe hi "dendritic" pattern of irregularly branching tributary systems resembling the branching pattern of a deciduous tree.
type II pattern or branching pattern is the most common pattern
The veins are branching up and down the leaf instead of branching up from a thick, center midrib.
