First of all, it is important to define what we consider an animal. An animal is any organism that contains DNA inside the nucleus, requires organic compounds made of carbon, and it is a multicellular organism. Simple bacteria were the only inhabitants of our planet around 650 million years ...
It is this specialization that allows multicellular organisms to develop complex structures such as leaves, eyes and brains. Hence the definition of a multicellular organism put forward by G. Bell and A. Mooers in 1997, that multicellular organisms are clones of cells that express different ...
The problem with defining Dark Matter is that it has never been proven nor disproven as to whether it is actually a living organism. What is the necessary combination of elements which create invisible matter? What scientific instruments are used to locate invisible space that actually has physi...
c) It gives rise to more complex forms, even the simpler ones continue to flourish. d) All of these . If one organism is said to be "more evolved" than another, what exactly does this mean? How the theory of evolution was developed? What's an example of a single spec...
Therefore, cells can potentially evolve to increase or decrease their rate of acceptance of horizontally acquired genes. In this paper, we ask if HGT is on average beneficial to the organism and whether selection will act to increase or decrease its rate. If HGT is frequent, the traditional ...
By 1970, two summer Investigators, Bodil Schmidt-Nielsen and Bill Kinter, had decided to become year-round Investigators at the MDIBL. Despite some space and administrative concerns, the move went smoothly, thus beginning the first attempt to evolve from
Life exists only on earth because of the following reasons:Earth has all the basic necessities that are required for an organism to survive.The temperature and atmosphere of the earth makes life comfortable for the organism. ... Earth has enough amount of water, food and air for survival of...
When it first evolved, literally nothing ate it because it was so new and no organism had the tools to break it down. So, during the carboniferous trees and plants with woody stems proliferated because they had few or no natural predators, and probably also because they could grow taller ...
--have not died out, have not yielded to the principle of Darwinian evolution. They remain in the same form they have had for eons. Why do they never "evolve" into something "higher?" The utilitarian aspect of the Theory of Evolution is also quite subjective. A species without hands has...
The Earth is thought to be over 4.5 billion years old. The first life that appeared on Earth was about 3.77 billion years ago. We cannot definitively say what the first organism was; our educated guess is that it must have been a prokaryote....
