Thanks to new fossil finds and analysis of ancient DNA preserved in teeth, bones and cave dirt, scientists have unearthed startling revelations about our Homo sapien forebears, and other humans that existed before -- and in some cases, alongside us. Here are six of this year's most ground-breaking discoveries in human prehistory that are shaping the family tree in fascinating and unexpected ways.

The first Americans. The footprints are thought to be made by children. Footprints made in muddy earth at the edge of a wetland, in what's now New Mexico, look like they could have been made yesterday. Read More. But they weren't. The discovery that the prints were pressed into the ground between 21, to 23, years ago has dramatically pushed back the history of humans in the Americas, the last continent to be settled by humans.

Until recently, the commonly held view was that people ventured into North America from Asia via Beringia, a land bridge that once connected the two continents, at the end of the ice age around 13, years ago. The tracks, thought to have been made by children, were made at a time when many scientists think that massive ice sheets sealed off human passage into North America, indicating that humans were there even earlier. Dragon man. Dragon man is the latest addition to the human family tree.

Described as the most important fossil discovery in 50 years, a cranium, which was hidden at the bottom of a well in northeastern China for more than 80 years, could represent a completely new type of human. The well-preserved skullcap, found in the Chinese city of Harbin, is between , and , years old, according to geochemical analysis. It combines primitive features, such as a broad nose and low brow and braincase, with those that are more similar to Homo sapiens, including flat and delicate cheekbones.

Researchers named the new hominin Homo longi, which is derived from Heilongjiang, or Black Dragon River, the province where the cranium was found. Colloquially, he's become known as Dragon Man since the discovery was made public in June. The hope is to extract DNA or other genetic material from the fossil to find out more about Dragon Man, particularly whether he may be a representative of the Denisovans, a little-known and enigmatic human population.

Biological process , cell migration, programmed necrobiosis apoptosis , differentiation, growth, and cell transcription remodel the inseminated gametocyte, an extremely specialized, ability cell, a zygote, into a multicellular person. Most changes occur throughout the embryonic and vertebrate periods; but, vital changes occur throughout later periods of development: time of life first four weeks , infancy first year , childhood 2 years to puberty , and adolescence 11 to nineteen years.

It is customary to divide human development into prenatal before birth and postpartum after birth periods. The most changes that occur prenatally square measure illustrated within the Timetable of Human prenatal development. Examination of the timetable reveals that the foremost visible advances occur throughout the third to eighth weeks— the embryonic amount.
