Why is there a gap in hominids between 3 mill BCE and 2 mill BCE?
Australopithecus africanus lived between 3 and 1 million years ago.
Australopithecus robustus is now known to have lived between 2.5 and 1.5 million years ago.
Australopithecus boisei lived between 2.5 and 1 million years ago.
Homo habilis also lived between 2.5 and 1.5 million years ago.
No doubt, further discoveries will continue to fill out this picture, but there is already a wealth of information about the early hominids who lived between 3 and 2 million years ago.
How can the big bang still be visible?
Light actually takes time to move, so light that was 13.7 billion light years away would just recently be visible, and we may be able to see the remnants of the big bang. many scientists predict that because they have predicted the universe is expanding and if you look back it makes sense that it all started at 1 point then.
I strongly disagree. I believe that human social and spiritual needs are just as important. If I didn't have caring people. the natural world, the arts around me, what is the point of life. These are the things that make life worth living.
Scientific view on how the world was made?
The scientific view on the creation of the world is based on the Big Bang theory, which suggests that the universe began as a hot, dense point and has been expanding ever since. Over billions of years, stars, galaxies, and planets formed through processes like gravity and nuclear fusion. Earth specifically formed about 4.5 billion years ago through the accretion of matter in a disk around the young sun.
That's a bit of a nonsense question. The existence of life is consistent with *any* and *every* hypothesis that tries to explain the existence of life, scientific or not. The existence of life is the very thing that the hypothesis is trying to explain, so necessarily the hypothesis assumes it and must therefore be consistent with it.
The same goes for the *kind* of life we find on Earth: since any scientific hypothesis must explain the life we find here, such a hypothesis must necessarily be consistent with the life we find.
What are all the known criteria to be considered human?
To be human, you must be a member of our species, Homo sapiens.
It was once thought that only humans expressed love, but it is now known that many mammals and even birds express love. It was once thought that only humans use tools, without being taught, but it is now known that chimpanzees learn to use tools. It was once thought that only humans have self-awareness, but it is now known that this is not true.
Humans form a species that excels in the ability to think, learn, love and understand, but none of these attributes is unique to humans.
When will the world start again?
The world never stopped—it's always in motion. If you're referring to a major event or change, it's hard to predict an exact time. Changes can happen gradually over time or suddenly due to unforeseen events.
Well, there isn't really any fact that says the universe is younger than we once thought, but scientists do speculate that the universe might be younger than we thought, because there are theoretical particles (like the graviton, a particle that creates gravity) that say the universe is younger than we think, but since the particles are just a theory, we don't actually know. It just depends on what information you choose to believe in. Currently, common science teachings say the universe is 13.69 billion years old, which is quite old.
What do you call a person against intelligent design?
A person against intelligent design may be referred to as an advocate for evolutionary theory, naturalism, or scientific materialism. They often reject the idea that the complexity of life is the result of a deliberate, supernatural creator.
How do the Japanese explain lightning?
In Japanese folklore, lightning is often associated with the deity Raijin, the god of thunder and lightning. Raijin is depicted as a powerful god who controls storms and is responsible for creating thunder and lightning by beating on drums. This mythological explanation helps to personify the natural phenomenon of lightning in Japanese culture.
What are the three theories of creation?
One theory is that a creator god, perhaps God, Ahura Mazda, Brahma or some other creator god, created the first life on earth. Some believe that God created life in all the forms we now have, while others believe that the present life forms evolved from the first divine beginnings. A second theory is that in early pre-Cambrian times, the Earth was hot and volcanic, lashed by violent electrical storms, and the atmosphere was rich in carbon dioxide, sulphur compounds and ozone. Conditions were ideal for chemical reactions to occur. Complex compounds began to form. Then inorganic molecules combined into even more complex organic compounds, gradually forming amino acids and proteins, the building blocks of life. Over millions of years, some of these compounds formed into simple cells, some of which had the capability to replicate themselves under certain conditions. A third theory is based on the ability of simple crystals to replicate themselves, even replicating any flaws or 'mutations'. Hydrocarbon molecules may have been attracted to the crystals and provided synergy in the replication process. Over millions of years, the process became more complex, while the hydrocarbon molecules began to become the primary components of these 'proto-cells'. Of course, the truth may have been a combination of this theory and the second theory above.
'Evolutionary time' can mean:-
1) 'A very long time'. Just like 'geological time', 'evolutionary time' invokes the idea of processes taking a very long time to occur.
2) 'Effective evolutionary time'. This is a hypothesis for explaining differences in species diversity at different latitudes. Mutation rates are faster and generation times are smaller at higher temperatures, making evolution tend to run faster in warmer climates.
What theories about the creation of the universe have been accepted in the past?
Until the second half of the twentieth century, the Steady State Theory predominated. This holds that the universe has always existed, very much as it does now. Stars may grow old and cold, but new stars are formed out of the abundant interstellar matter. So, the universe will continue to exist as it does now, for many billions of years.
While the Steady State Theory may still have some adherents, the predominant theory among scientists is called the Big Bang Theory. This holds that, about 13.7 billion years ago, an infinitessimally small point exploded to produce the entire universe. Once again, stars may grow old and cold, and new stars form out of the abundant interstellar matter, but the difficulty of infinite existence does not apply. There are at least two, somewhat compatible, hypotheses as to what formed the infinitessimally small point and triggered the Big Bang.
Some scientists believe that the process that triggered the Big Bang could have occurred more than once. If so, there could be many universes, in what has been termed a multiverse. However, we will probably never become physically aware of any of the other universes.
A scientific theory is supported by evidence. Without evidence, it is only a hypothesis.
How do organisms change over time according to evolutionary theory?
Organisms change over time through the process of natural selection, genetic mutations, and genetic recombination. Over generations, advantageous traits are favored, leading to the accumulation of genetic changes in a population, resulting in biological diversity and adaptation to the environment. This process is at the core of evolutionary theory, explaining how organisms have evolved and diversified over millions of years.
How did life begin according to the evolutionary theory?
The Theory of Evolution does not seek to how life began, although there are several very credible hypotheses for the beginning of life on Earth.
The traditional view is that, billions of years ago while the Earth was still hot and there was extreme volcanic and lightning activity, organic chemicals began to form out of the simpler inorganic chmicals that abounded. These organic chemicals became more and more complex, until RNA molecules (the precursors to DNA) formed. Once RNA, and then DNA molecules existed, life was ready to begin.
Another hypothesis is based on the ability of some crystals to replicate themselves, even replicating the defects that occasionally formed. In a 'dirty' environment, carbon atoms could attach themselves to those crystals and become replicated along with the crystal itself. This self-replication is not yet life, but could conceivably lead to the development of life.
Evolution say the world was created how?
Evolution does not propose that the world was created. Instead, it explains how life forms have changed and adapted over billions of years through natural selection and genetic variation. The theory of evolution is focused on the development of life on Earth, not the creation of the Earth itself.
According to Urban Dictionary, Orgism refers to the creation of a parallel universe.
How the big crunch theory explain the universe?
The big crunch theory suggests that the expansion of the universe will eventually reverse, causing all matter to collapse back in on itself. This would result in a dense, hot state similar to the Big Bang. However, current observations indicate that the universe is not only expanding but accelerating, making a Big Crunch scenario less likely.
How did God create the big bang?
The question is illogically formulated. According to those that believe in God,there was no Big Bang. The concept of God and creation is such that Godwilledcreation into existence. According to creationists God didn't create or cause the Big Bang because, not being mentioned in the Bible/Torah, it never happened.
According to scientists, there is no empirical evidence forthe concept of God. Subsequently, there are no theories that include or rationalize a God-like creation. While some even talk about the concept of a'god' particle that started the process, this is more of a media term than a recognized scientific acknowledgement for the concept ofGod.
What should a scientific test be?
A scientific test for Creation should be fair. There are only 2 choices to explain creation:
_Creation by Evolution
_Special Creation by God.
There are no other real choices, and if one is disproved then it must be the other. It all depends on ideology, but unfortunately some hold to one ideology regardless of facts. It is all a process of elimination:
-scientific facts can be used to prove creation,
but
-evolution cannot be proved by scientific facts
One of the two absolutely basic tenets of Science is that any scientific experiment should be able to be replicated. This means being done again exactly the same way as the first and getting the exact same result. As this would be impossible - it would mean "de-creating" everything first to prove an idelogical theory - it means there can be no scientific proof for Creation.
The second of the two absolutely basic tenets is that Science can only deal with the "here and now", the present time. Science cannot explain where matter for the Big Bang originally came from and what things were like before any 'Big Bang'. Any attempt to do so means Science is dealing with Religous matters.
This means there can be simply no scientific test at allfor creation.
What is a scientific view on creationism?
The scientific view on creationism is that it is not supported by empirical evidence or scientific consensus. Evolutionary theory, supported by a vast body of evidence, is widely accepted by the scientific community as the explanation for the diversity of life on Earth. Creationism, which posits divine intervention as the origin of species, is considered a belief system based on faith rather than scientific inquiry.
Is creationism an official scientific theory?
Regardless of what its supporters claim or would like to believe, they are a very tiny minority. 99.9% of scientists accept the current mainstream views such as the Big Bang theory and the thmodern evolutionary synthesis, and have in the process invalidated creationism as a viable alternative.
How long has the Creation hypothesis been supported?
In some form or another it has always been supported. It kind of took a back seat to other scientific theories such as geology and evolution around the 1800s, but has made a strong comeback in the last 30 years or so. Nothing supports it. It is not a scientific theory.
Where did the dense singularity originate that existed before the Big Bang?
In a universe model, the term 'where' in context of a singularity has no meaning. Our understanding of spacial geometry, which we use to estimate where we are, depends upon our positional relationship to our known universe. But if the universe is infinitessimally small, then there is no measurement of position, because everything is in the same place.
.
In a multiverse model, in which there are several universes coexisting in adjacent parcels of space at the same time, then the term 'where' is definable, but not measurable. In this case, we could say that the singularity is so many billion/trillion/quadrillion light years from the next closest universe, but we have no means of measuring distances that large.
