Human Origins

The common cold is caused by many different viruses that mutate rapidly, making it challenging for humans to develop a specific resistance. Additionally, the symptoms of the common cold are not severe enough to exert strong evolutionary pressure for resistance to develop.

It is not possible to determine the exact cause of death for a specific individual of Australopithecus afarensis. However, factors such as predation, disease, environmental changes, accidents, and natural disasters could have contributed to their mortality.

There's no doubt about it - man came after plants . Plants are our earliest known ancestors . They have all that we have - except mobility .

Assimilation model, multiregional continuity model, and out of Africa model

The Out of Africa theory posits that Homo sapiens originated in Africa and then migrated to populate the rest of the world. This theory is supported by genetic evidence and fossil records.

Max Weber traced the origins of the capitalist economy in Europe to the Protestant Reformation, particularly the values and beliefs of the Protestant work ethic. Weber argued that the Calvinist emphasis on hard work, frugality, and worldly success played a significant role in shaping the development of capitalism in Western societies.

Archaic H. sapiens appeared in the period beginning 500,000 years ago. They H. heidelbergensis, H. rhodesiensis, H. neanderthalensis and sometimes H.antecessor

Anatomically modern humans appeared about 400,000 years ago.

The bacteria kingdom was discovered by Anton van Leeuwenhoek in the 17th century. Leeuwenhoek is considered the father of microbiology for his pioneering work in observing and documenting microorganisms, including bacteria, using a microscope.

Lucy, a hominin fossil discovered in Ethiopia in 1974, died approximately 3.2 million years ago. The exact cause of her death is not known, as it is impossible to determine how an individual died from their fossil alone.

The exact location or region of the first land inhabited by humans is still under debate by scholars. However, it is believed that early human ancestors first emerged in Africa before migrating to other parts of the world.

Homo erectus is a species of early human that evolved in Africa around 2 million years ago. There is no single inventor of Homo erectus; it is a result of a series of evolutionary changes that occurred over time in the human lineage.

It means scientist using clone technology to breed a super-human, as it may be called. Humans have intervened in the natural selection of the species by using medical means to prolong life and to allow people to procreate when they could not have done so naturally. (This only affects the natural selection of the species when it affects whether or not a person can procreate, so medical intervention that prolongs life well after the age of being able to procreate is unlikely to have an effect on natural selection, unless it allows procreation with aged and therefore less healthy sperm or eggs.) This will eventually have an effect on the species by increasing the likelihood of heritable traits being passed on that are not to the benefit of the species. Evolution by human intervention would require that the intervention changes the set of people able to procreate. In vitro fertilisation would be one means by which this occurs if the difficulty with conceiving is a heritable one. The abortion of foetuses of the less desired sex, or bearing undesired traits or diseases is another.

Homo sapiens have a highly developed brain with complex cognitive abilities, including language, abstract thinking, and problem-solving skills. They also have a more advanced capacity for social cooperation and cultural transmission. Additionally, Homo sapiens exhibit a wide range of diverse behaviors and adaptations that have allowed them to inhabit and thrive in various environments across the globe.

The Leakeys are a family of paleoanthropologists known for their discoveries of early human fossils in East Africa. Louis, Mary, and Richard Leakey have all made significant contributions to our understanding of human evolution, particularly in places like Olduvai Gorge and Lake Turkana. Their work has helped shape our knowledge of our ancestors and how humans have evolved over time.

"Homo erectus" means "upright man" in Latin, a name that reflects the species' distinctive upright posture and bipedal locomotion. The name was first proposed by paleoanthropologist Eugène Dubois in 1892 based on fossil remains he discovered in Java.

After doing some research on this matter the consensus is that they did not use fire. I saw a few threads where people believe they did but that would be near the end of their existence.The timeline is very long for these beings and the evidence is hard to discern.

Homo sapiens are the scientific name for modern humans. They have a relatively hairless body with a high, rounded skull, vertical forehead, and small teeth compared to other hominid species. Homo sapiens also have a prominent chin and a lighter skeletal structure.

Homo sapiens are omnivores, meaning they consume both plants and meat as part of their diet. The ability to eat a variety of foods contributed to the success of the species in adapting to different environments and obtaining essential nutrients.

Homo sapiens are believed to have evolved from an earlier species, Homo erectus. Once hominids emerged around 2 million years ago, they migrated from Africa and populated the other continents. Several species of hominids existed simultaneously.

The earlier hominids included some which were much larger and more powerful than today's humans, and some smaller and weaker. They were not stoop-shouldered with short bow-legs and long arms, with hands dragging on the ground. They were just as upright as modern man, with feet and legs adapted to walking upright. There were also other great apes that (like today's chimps, gorillas and orang-utans) were not adapted to ground dwelling and thus never came into ecological competition with humans.

Today there are only 4 genera of great apes left -- Chimps, Gorillas, Orang-utans and humans. For a while, Gibbons were included in that group because they can raise their forearms above their heads like the other apes (old-world monkeys can't do that). But they are so different that they have been grouped in a class of their own.

Humans appeared during the Quaternary period of the Cenozoic era, which began around 2.6 million years ago. This era is marked by the development of modern human species and the emergence of Homo sapiens.

The pituitary gland secretes hormones that help regulate growth. When it stops producing certain hormones, you stop growing.

There can be problems with being too large, so humans have evolved over time to have the proper amount of hormones produced (which can vary a bit). People with malfunctioning pituitary glands, can have a variety of problematic growth disorders.

Yes, a floating egg experiment is a suitable and engaging science experiment for 6th grade students. It can help them learn about density, buoyancy, and the scientific method in a hands-on way. Just ensure they have adult supervision when handling the eggs and water.

A missing link is something necessary to complete a series, like an animal fossil that has not yet been found to prove that apes evolved into humans. A missing link is an argument against evolution, claiming that it cannot be true just because we are lacking some fossils to prove i. However it could be argued that since we haven't even found all of the animals alive yet, there is no way we could know everything that has ever lived.

Half of all missing link fossils have been found in whole or part. Tiktaalik is a very important one connecting fish to tetra-pods.

Nobody can tell you exactly. However the word will cease to exist when the Sun expands to become a red giant (at which point the Earth will be inside the Sun).

This will happen between 4 and 5 billion years in the future. The Earth has been around for about 3.5 billion years.
