What was the first cell that evolved?

The first cells were most likely primitive prokaryotic-like cells, even more simplistic than these E. coli bacteria. The first cells were probably no more than organic compounds, such as a simplistic RNA, surrounded by a membrane.

Do we know how the first cell was formed?

The first cell is presumed to have arisen by the enclosure of self-replicating RNA in a membrane composed of phospholipids (Figure 1.4). Such a phospholipid bilayer forms a stable barrier between two aqueous compartments—for example, separating the interior of the cell from its external environment.

Why is the cell considered to be complex?

The cell is the most complex and most elegantly designed system man has ever witnessed. The reason is that organic molecules are so complex that their formation cannot possibly be explained as being coincidental and it is manifestly impossible for an organic cell to have been formed by chance.

How did scientists explain the origin of the first cell?

A generation ago, scientists believed that membranous droplets formed spontaneously. These membranous droplets, called protocells, were presumed to be the first cells. Modern scientists believe, however, that protocells do not carry any genetic information and lack the internal organization of cells.

Which theory is accepted today regarding the origin of evolution?

Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment.

What needs to happen in order for evolution to occur?

In order for evolution to occur two things need to be present: genetic variation and some sort of stress.

What odds are considered mathematically impossible?

A statistical impossibility is a probability that is so low as to not be worthy of mentioning. Sometimes it is quoted as 10−50 although the cutoff is inherently arbitrary. Although not truly impossible the probability is low enough so as to not bear mention in a rational, reasonable argument.

What is the relationship between the improved microscope and the discoveries made by scientists about cells?

Explanation: With the development and improvement of the light microscope, the theory created by Sir Robert Hooke that organisms would be made of cells was confirmed as scientist were able to actually see cells in tissues placed under the microscope.

Why do we use microscopes to study cells?

A cell is the smallest unit of life. Most cells are so tiny that they cannot be seen with the naked eye. Therefore, scientists use microscopes to study cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.

Is there a probability argument against evolution?

Note that there is no comparable opposition movement to quantum physics, organic chemistry, cetacean biology or any of a host of other scientific theories. Both traditional creationists and intelligent design writers have invoked probability arguments in their criticisms of evolution.

What are the chances of meiosis forming a DNA molecule randomly?

If we were to compute the chances of the formation of a human DNA molecule during meiosis, using a simple-minded back-of-the-envelope probability calculation similar to that mentioned above, the result would be something on the order of one in 10 1,000,000,000, which is far, far beyond the possibility of “random” assemblage.

What is a failure to clearly define the probability space?

A failure to clearly define the probability space in this way is often the source of fallacious arguments.
