Information obtained from early-human fossils and archaeological remains suggests that there were 15 to 20 different species of early humans several million years ago. With the exception of a few atoms produced by radioactive decay, every atom in your body already existed when the Earth formed around 4.5 billion years ago. Thanks to their unique memory and ability to acquire language skills and write, humans around the world, from the very young to the very old, have been communicating and transmitting their ideas through stories for thousands of years, and storytelling remains integral to being human and to human culture.

The theories in science are always being reconsidered and scrutinized. “Earth - The Real Reasons Why We Walk on Two Legs, and Not Four.” BBC, BBC, 12 Dec. 2016, www.bbc.com/earth/story/20161209-the-real-reasons-why-we-walk-on-two-legs-and-not-four. He says, "Episodic memory is probably closest to what we typically mean when we use the word 'remember' rather than 'know.'" In fact, your atoms have been in pretty well every type of living thing, from trees to grass, insects to dogs. Most other mammals have a ratio of only 1-to-180. Here we quantify the human-made mass, referred to as ‘anthropogenic mass’, and compare it to the overall living biomass on Earth, which currently equals approximately 1.1 teratonnes10,11. The ability to speak and develop language was an enormous advantage for humans. • “Mead Project Source Page, A.” Charles Darwin: The Expression of the Emotions in Man and Animals: Chapter 13, brocku.ca/MeadProject/Darwin/Darwin_1872_13.html. Forethought also allows humans generative and creative abilities unlike those of any other species. Information obtained from early-human fossils and archaeological remains suggests that there were 15 to 20 different species of early humans several million years ago. The scientists knew at some point we would reach a crossover point. At the basic level, you are made of just four types of particles, which have been around for the majority of the lifetime of the Universe. The most genuine merit of science is probably its readiness to admit its mistakes (usually!). “Chimps, Humans and Monkeys: What's the Difference?” Jane Goodall's Good for All News, 11 Sept. 2018, news.janegoodall.org/2018/06/27/chimps-humans-monkeys-whats-difference/. What we’ve seen so far is a physicist’s view. Regardless of one's religious beliefs and thoughts about what happens after death, the truth is that, unlike other species who live blissfully unaware of their impending demise, most humans are conscious of the fact that someday they will die. We are now the only living members of what many zoologists refer to as the human … One persistent myth is that this virus, called SARS-CoV-2, was made by scientists and escaped from a lab in Wuhan, China, where the outbreak began. Unitarian Universalist minister Forrest Church (1948-2009) explained his understanding of religion as "our human response to the dual reality of being alive and having to die. • Masterson, Kathleen. When compared to other species, human beings are extremely advanced and anomalous. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE. In my new book What Do You Think You Are? Marder, Lisa. Evolutionary biology and scientific evidence tell us that all humans evolved from apelike ancestors more than 6 million years ago in Africa. To see why, consider the oxygen and hydrogen. Dr. Varki found that the addition of just one oxygen molecule in the polysaccharide that covers the cell surface differentiates humans from all other animals. Humans also have an abundance of sweat glands, called eccrine glands. Given that it is involuntary, blushing is considered to be an authentic expression of emotion. Modern research often rejects old ideas, hoaxes and myths. These are the familiar particles making up the central nucleus of an atom, but each has sub-components. A human being (i.e., a human organism) is composed of human parts (cells, proteins, RNA, DNA), yet it is different from a mere collection of cells because it has the characteristic molecular composition and behavior of an organism: it acts in an interdependent and coordinated manner to “carry on the activities of life.” Giving man not only an earthly origin but a realistic assessment of what are humans made of scientifically hydrogen information from!
