A virtual revolution occurred in the creation of art during the period of the Upper Paleolithic in Europe. Beginning around 40‚000 B.C.‚ the archaeological record shows that anatomically modern humans effectively replaced Neanderthals and remained the sole hominid inhabitants across continental Europe. At about the same time‚ and directly linked to this development‚ the earliest art was created. These initial creative achievements fall into one of two broad categories.

The dial may be located either on the handset‚ or on a base unit to which the handset is connected by a cord containing wires. A landline telephone is connected by a pair of wires to the telephone network‚ while a mobile phone‚ such as a cellular phone‚ is portable and communicates with the telephone network by radio transmissions.

three billion base pairs of chromosomes. Also‚ vital to note is the fact that though the human genome has been read by DNA sequencing‚ it is still not well understood. Simply put‚ the human genome is a set of human genetic information that is stored as DNA sequences. We have what is called the haploid human genome and the diploid human genome. The haploid human genome can be found in the egg and sperm cells. Research shows that this genome has about three billion DNA base pairs. On the other hand

James Watson and Francis Crick figured out the structure of DNA. DNA is a double helix. The structure of DNA can be likened to a twisted ladder. The rungs of the ladder are made up of “bases” Adenine (A) is a base. Thymine (T) is a base. Cytosine (C) is a base Guanine (G) is a base. A always pairs with T in DNA. C also pairs with G in DNA. The amount of A is equal to the amoun tof T‚ same for C and G. A+C = T+G Hydrogen bonds hold the bases together
