Misterioso “oxigênio negro” pode mudar o que sabemos sobre a vida

Cientistas descobriram que o oxigênio vem de nódulos polimetálicos e não de organismos vivos.

A descoberta coloca em questão a teoria sobre as origens da vida.

O "oxigênio negro" é produzido diferente da fotossíntese, a mais de 4.000 metros de profundidade.

A visão convencional é que o oxigênio começou a ser produzido há cerca de 3 bilhões de anos por cianobactérias.

Mas, este estudo todo levantou uma questão: A vida poderia ter começado em lugares diferentes da superfície terrestre e perto da superfície do oceano.'
