‘order’ISapparent everywhere. Over the eons a chaotic universe organised itself into stars, planets and galaxies. Here on Earth, atoms became ordered or integrated to form molecules→which in turn integrated to form compounds→virus-like organisms→single-celled organisms→multicellular organisms→and...

The first form of life to develop on the Earth were microbes, and they remained the only form of life on the planet until about a billion years ago when multi-cellular organisms began to appear.[61] Microorganisms are single-celled organisms that are generally microscopic, and smaller than th...
What is the classification of amoeba? To what phylum do paramecium belong? How is an amoeba like an animal? How do you culture amoeba and paramecium? What kind of organisms are amoebas? Is an amoeba a multi-celled organism? Which of these protists moves the fastest, amoeba or paramecium?
are truly ancient animals. They arrived on land close to a billion years ago and may well have colonized continents that were then home only to films of bacteria. Slime molds, or Physarum polycephalum, may spend much of their lives as single-celled organisms but are also...

The “father of marine biology” is often considered to be Charles Darwin due to his groundbreaking work on the theory of natural selection and his detailed studies of marine organisms during his voyage on the HMS Beagle. Will marine biologists be needed in the future?
Life has been on its way to dominating planet Earth for the past 3.7 billion years. What started as microbes and single-celled organisms have evolved into giant multi-cellular plants and animals capable of doing many complex things. It was a long journey to get here, and many factors had ...
Behold, the true nature of bantha fur, as I have seen with microdroid holo-imaging: it is a second, external circulatory system of sorts. Simply put, the hairs have a thermo-conductive submolecular structure that deflects heat (and even, to a degree, the energy of a blaster) and traps...
