In considering the theory of human evolution it is interesting to note that some very well known scientists have actually suggested that the line of human evolution is far from clear. For example, in 1990, Richard Leakey himself said that, "If pressed about man's ancestry, I would have to ...
In humans and other animals, harsh circumstances in early life predict morbidity and mortality in adulthood. Multiple adverse conditions are thought to be especially toxic, but this hypothesis has rarely been tested in a prospective, longitudinal framewo
“The pace of AI development over the past 22 months has surpassed any historical period, yet we remain in the early stages of the AGI transformation,” Wu said in a keynote at Apsara Conference 2024, an annual tech event organized by Alibaba Cloud Intelligence Group (Alibaba Cloud). "Histo...
Zinc deficiency during pregnancy and postnatal life can adversely increase risk of developing human diseases at adulthood. The present study was designed to evaluate whether dietary zinc deficiency or supplementation during the pregnancy, lactation and juvenile stages interferes in the development of mammary...
evolutionary and phylogenetic stages in the evolution of the mammalian middle ear, the postdentary-attached middle ear (PAME), the Meckelian-attached middle ear (MAME), and the detached middle ear (DME)7,8,9. In addition, the evidence for embryonic development of the middle ear and mandible...

(see below), this pattern of most of the adult tooth row being in place during the first 2 years of life is also supportive of a relatively short (compared with its total lifespan) juvenile stage46and determinate growth47. The absolute length of these stages inMorganucodonis, however, ...
The human cortex comprises diverse cell types that emerge from an initially uniform neuroepithelium that gives rise to radial glia, the neural stem cells of the cortex. To characterize the earliest stages of human brain development, we performed single-cell RNA-sequencing across regions of the deve...
Man went through many stages to evolve into the humans of today! Since this evolution covers roughly 3 million years, you might say it took man a long time to grow up! Early Humans What is a hunter-gatherer? What is a Stone Age? Why was the ability to make fire so important? How ...
