Philip Kerourio debunked Erben and others' suggestion that an increase in the incidence of pathological eggs in dinosaurs led to their extinction. He found that only 0.5–2.5% of eggs in the area Erben and the others studied had multiple shell layers and observed no evidence that these pathologies became more common through the Late Cretaceous ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga.
