The deserts are actually one of the most common and widespread landscapes on the planet Earth. The deserts, combined of all types, are covering around 33% of the landmass, thus one third of the whole landmass on the planet.
These multiple types of deserts, like the hot and dry desert type, cold desert, coastal desert, semiarid desert. All of them have their own unique characteristics that define them more specifically. The hot and dry deserts are the ones that are hot throughout all of the year, also being located deeper into the mainland. The cold deserts are found in the Northern Hemisphere, they have hot summers and very cold winters. The coastal deserts are located along the coasts, so despite being very dry, they do tend to have high humidity. The semiarid deserts are deserts that are not as dry as the other types, they receive more rainfall, though that happens just in few days of the year, so they are dry for the most of it again, with the biggest difference being that they have slightly more vegetation.
Answer:
Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.
Explanation:
As you have seen in the question above, lycanthropy is a mutation that is more likely to be established as the supply of male gametes comes from older men. This is because sperm undergo more mitotic cell divisions than eggs, and therefore are at greater risk of developing a spontaneous mutation.
In order for you to understand this, you need to know that eggs (which are female gametes) are produced at once in a woman's body. Thus, cell division is limited and therefore the opportunity for spontaneous mutations to occur is also limited. However, men produce sperm from adolescence to death, creating the need for countless cell divisions, which can develop genetic errors that create spontaneous mutations in gametes.
Around 100,000 years ago there was a second hominine species closely related to modern humans, Homo <span><span>neanderthalensis,</span><span> or commonly called the Neanderthal</span>.</span> Recent studies of neanderthal DNA have shown that there is 3-4% of their genes in modern humans outside of Africa, mostly from Europe, including the ones for adapting to the cold and vitamin D absorption.
