<span>This finding that all known organisms use genetic information to produce protein molecules via the same genetic code strongly supports the hypothesis that all organisms are descended from a single common ancestor.
Genetic information is the biological information coded in the dna or rna sequences, like chromosomes.
A specie from which two different species are evolved is a common ancestor.</span>
Answer:
Graph showing known historically active volcanoes, number of volcanoes reported to be active each year, and population. The line labeled "Known Historically Active Volcanoes" (right scale) is the cumulative number of volcanoes with an historically recorded eruption by that year. "Volcanoes Active Per Year" since 1400 CE (black line) and 10-year running mean of same data (thick red line) is also based on reported eruptions (those with uncertainty dates greater than 1 year are not included, nor are uncertain eruptions). "Population" (right scale) is the world's estimated human population; data from McEvedy and Jones (1978) and (since 1750) Population Reference Bureau, Washington, D.C. See text for further explanation.
A dramatic increase in both the number of historically active volcanoes and recorded eruptions took place about 1500 CE. These resulted in part from the great Spanish/Portuguese marine explorations – the Age of Discovery – around the end of the 15th century, when explorers opened Latin America and much of the western Pacific to European record-keeping. Perhaps equally important was the development and widespread distribution of the printing press in the late 15th century, markedly increasing the likelihood that new volcanological records would survive. Through the 17th and into the early 18th century the recognition of additional active volcanoes generally corresponded with steadily increasing eruption reports. By the 18th century global trade was flourishing, the Industrial Revolution was under way, and the heightened reporting of eruptions noticeably accelerated the discovery of new volcanoes. The list has continued to grow, with several important volcanic regions such as New Zealand, Alaska, and Hawaii being unrepresented until the last 250 years.

There are four nitrogenous bases<span> found in </span>DNA<span> that are called guanine, adenine, thymine and cytosine.</span>They<span> are abbreviated by the first letter in their name, or G, A, T and C. The </span>bases<span> can be divided into two categories: Thymine and cytosine are called pyrimidines, and adenine and guanine are called purines.</span>
The answer is George Mendel. He is known as a father of genetics because of his work on pea plant. He discovered that genes are present in a form of pair and there are two alleles to a single gene which manifest the traits.
His work with pea plant clearly explains the fact that there are two alleles of a single gene, for example:
Pea shape- round or wrinkled
Pod color- green or yellow
He is know as father of genetics by introducing The law of inheritance
