Of course we can survive without clothes. We evolved a hairless body because our ancestor was an ape that was forced to live in the hot, open savanna, where fur is not needed. In fact, many people around the world did not wear any clothes. Native Hawaiians, for example, wore no clothes when the first European explorers arrived. Amazonians and Africans also did not wear clothes. Humans evolved in Africa about 150,000 years ago, and the early humans wore no clothes. Humans started migrating out of Africa about 60,000 to 70,000 years ago. They followed the coast line and went all the way to Australia. These early migrants ended up in places that required no clothes. Only when humans migrated to places like ice age Europe and northern parts of Asia (northern parts of China, Japan and Korea) did they need to wear clothes or animal skins to stay warm. Wearing clothes blocks out the sun and these people were in danger of vitamin D deficiency, which leads to rickets. Rickets can result in muscle cramps, broken or deformed bones and even death. In order to absorb enough UV light to synthesize vitamin D, there was strong selection pressure to evolve lighter skin tones.
The habit of wearing clothes, even in places that do not require them, was spread by European Christians. Basically they forced and/or shamed the natives to wear clothes wherever they went.Of course, not wearing clothes means that humans will no longer be able to live in temperate areas around the world, at least not during the fall and winter months.
Answer:
D
Explanation:
Enzymes are chemical catalysts they speed up/ increase the rate of the reaction by lowering the activation energy (minimum energy required for reaction to actually occur).
I'm 100% that the answer is D, thermal conductivity.
It was either C or D but D makes more sense than C does
so your answer is D
The object will continue to move north because there is no opposing force form the south and the other forces canceled each other out
Answer:
Animal clade
Explanation:
<em>A clade is used to refer to all members of group of organisms that share the same ancestor.</em>
Animals are the only group of living organisms that are eukaryotic, multicellular as well as heterotrophic in nature.
They are eukaryotic because their cells have nucleus and membrane-bound organelles like mitochondrion and chloroplast.
They are multicellular because their bodies are made up of more than one cells. The simplest animal (sponge) is made up of several cells while the most complex animal (human) is made up of millions of cells.
Animals are heterotrophs because they lack the capacity to manufacture their own food. They depend on external source for their food. Particular, animals ingest their foods, digest it internally and egest undigested food/waste materials.
