Nearly all of these proteins can be explained by a single gene family, so this means that the diversity of silk types we see today is encoded by one gene family, so presumably the original spider ancestor made one kind of silk, and over the last 380 million years, that one silk gene has duplicated and then diverged, specialized, over and over and over again, to get
Aproape toate aceste proteine pot fi explicate printr-o singura gena familiala, deci asta inseamna ca diversitatea tipurilor de matase pe care o observam azi este criptata intr-o singura gena familiala deci in mod prezumtiv, paianjenul ancestral producea un singur tip de matase si de-a lungul a peste 380 de milioane de ani aceasta unica gena de matase s-a divizat, apoi a creat divergente, apoi s-a specializat, iarasi si iarasi si iarasi pana a ajuns
