The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
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. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates. [1]The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia.

Around 380 to 375 Ma, the first tetrapods evolved from fish. [171] Fins evolved to become limbs that the first tetrapods used to lift their heads out of the water to breathe air. This would let them live in oxygen-poor water, or pursue small prey in shallow water. [171] They may have later ventured on land for brief periods.
The American company Gorton-Pew Fisheries, now known as Gorton's, was the first company to introduce a frozen ready-to-cook fish finger; the product, named Gorton's Fish Sticks, won the Parents magazine Seal of Approval in 1956. [129] [130] The developer of those fish sticks was Aaron L. Brody. Seafood USA 1953
The earliest Earth crust probably forms similarly out of similar material. On Earth the pluvial period starts, in which the Earth's crust cools enough to let oceans form. c. 4,404 Ma – First known mineral, found at Jack Hills in Western Australia. Detrital zircons show presence of a solid crust and liquid water.
Wilcox claims the fries "have had the same hot and crispy taste since 1955," only altering slightly since the fast food chain's inception. In 1990, McDonald's began cooking fries in cholesterol ...
This used the intense mechanical working of dough, and control of gases touching dough, to dramatically reduce the fermentation period and the time taken to produce a loaf at the expense of taste and nutrition. [39] For generations, white bread was the preferred bread of the rich while the poor ate dark (whole grain) bread.
