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. [2] The earliest evidence of life found in a stratigraphic unit, not just a single mineral grain, is the 3.7 Ga metasedimentary rocks containing ...
First hominid in space. Ham (July 1957 – January 19, 1983), a chimpanzee also known as Ham the Chimp and Ham the Astrochimp, was the first great ape launched into space. On January 31, 1961, Ham flew a suborbital flight on the Mercury-Redstone 2 mission, part of the U.S. space program's Project Mercury. [1][2]
Tardigrades have barrel-shaped bodies with four pairs of stubby legs. Most range from 0.3 to 0.5 mm (0.012 to 0.020 in) in length, although the largest species may reach 1.2 mm (0.047 in). [ 10 ] The body consists of a head, three body segments each with a pair of legs, and a caudal segment with a fourth pair of legs.
Drosophila melanogaster, the common fruit fly, has been used to study the effects of spaceflight on living organisms.. On a July 9, 1946, suborbital V-2 rocket flight, fruit flies became the first living and sentient organisms to go to space, and on February 20, 1947, fruit flies safely returned from a suborbital space flight, which paved the way for human exploration.
Last universal common ancestor. The last universal common ancestor (LUCA) is the hypothesized common ancestral cell from which the three domains of life, the Bacteria, the Archaea, and the Eukarya originated. The cell had a lipid bilayer; it possessed the genetic code and ribosomes which translated from DNA or RNA to proteins.
The mythical Gaia was the primal Greek goddess personifying the Earth, the Greek version of "Mother Nature" (from Ge = Earth, and Aia = PIE grandmother), or the Earth Mother. James Lovelock gave this name to his hypothesis after a suggestion from the novelist William Golding , who was living in the same village as Lovelock at the time ...
