The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. [1] [2] [3] They are estimated to constitute 1% of ...
For much of the Paleozoic Era (542–251 Ma), the fungi appear to have been aquatic and consisted of organisms similar to the extant Chytrids in having flagellum-bearing spores. [14] Phylogenetic analyses suggest that the flagellum was lost early in the evolutionary history of the fungi, and consequently, the majority of fungal species lack a ...
Frederick Accum was the first to raise alarm to the food adulteration in 1820. In 1837, American health reformer Sylvester Graham published Treatise on Bread and Bread-Making , which described how to use unrefined wheat flour to make Graham bread at home, in response to adulterated bread sold in public bake houses.
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.
