My vampire hunting homies will recognize this Death from Symphony of the Night.
600 million years, give or take. According to the Wikipedia entry for Ediacaran fauna (one of my favorite faunas ever), the first megafossils show up 610 million years ago, but I haven’t found any other references to back that up. The “Snowball Earth” glacial marine rocks of the Glaskiers formation show up around 595 Ma, with the iconic Drook formation being slightly younger, so I’m curious about how they came up with that number. The Wikipedia page for the Cambrian explosion seems to indicate 580 Ma, the page for the Doushantuo formation cites its base at 595 Ma, but I recall a PZ Myers post asserted that there is a wide range of uncertainty about these strata.
Vernanimalcula, the possible ancestor of all Bilateria, is dated to roughly 600 Ma.
Confusing, if you ask me.

Death is what makes life worth living.

Depending on the field, 1/4, 1/3, 1/2, even 2/3 or more of life is spent learning the known. For the scientist who desires to learn something new, to create knowledge, to contribute to civilization, it’s a race against time.
Until aging is no more, the human brain remains woefully underused.
Evolutions ARE stupid.
