Evolutionary history of the alpha2,8-sialyltransferase (ST8Sia) gene family: Tandem duplications in early deuterostomes explain most of the diversity found in the vertebrate ST8Sia genes

Table 1 Regression equations of linearized distances versus million years ago (MYA).

ST8Sia group	Regression equations	Determination coefficient	Significance
ST8Sia II/ST8Sia IV	y = 920x + 296	R² = 0,90	p = 0.00085 (eq1)
ST8Sia III/ST8Sia III-r	y = 752x + 326	R² = 0,90	p = 0.025 (eq2)
ST8Sia I/ST8Sia V/ST8Sia VI/ST8Sia VII	y = 430x + 313	R² = 0.88	P < 0.001 (eq3)
