When evolution started?

Answer 1

In living organisms, evolution started in the very first living cell that contained mutable nucleic acid. The instant a reproductive living organism ( immediately post-abiogenesis) that contained a nucleic acid, evolution could begin. This would have happened in the first life of the Precambrian (3 800 million years ago).

In the world of anthropic learning and discovering the Universe, Charles Darwin thought up a name for the mechanism of evolution in the 1800s and published On the Origin of Species in 1859. In other words the world has known about evolution since 1859.

Answer 2

In 1859 when Darwin published his book on the theory of evolution by natural selection. Darwin and Wallace had their two papers read out at the Linnaen Society in 1858 but no one took any real notice of that. After Darwin's book was published the religious and scientific debates began. Some of the scientific debates were interesting, such as the criticisms of Darwin's mechanism of heredity, but the religious objections to the theory were as they are now; incoherent.

Most scientists by the time of Darwin knew evolution was taking place but they did not have a mechanism for the process. Darwin provided that and when he did he seemed to provide the ammunition to the scientific objectors to his theory. From saltationism to the epigenetics of this day the debate continues, but the theory still stands and is still well supported by the evidence.

Answer 3

This question can be interpreted several different ways, and you might need to clarify for better answer.

How did the theory of evolution begin? Although many believe that Charles Darwin was the first to hypothesize the theory of evolution, many Eastern civilizations believed that organisms changed over time (which is basically evolution). What Darwin did was put a supported process behind the observational fact that organisms change over time. He popularized his theory with the publication of "On the Origin of Species," which led to the wide-spread acceptance of evolution emerging in the mid 1940's among the Western scientific community.

How did the process of evolution begin? The better question is, "what drives the process of evolution?" Evolution is driven by multiple mechanisms, but relies primarily on the two most famous:

* Natural selection: Darwin's principal that organisms change over time based on their need to adapt to their natural surroundings. * Genetic drift: Random mutations in the genetic code enabling the selective process of natural selection. Those two mechanisms are the main driving force behind the well-known fact that organisms change over time.

Evolution began in the very first set of organisms on Earth -- how those organisms were created is not a question left to the theory of evolution, but rather a question that is explained by the theory of abiogenesis (which is not spontaneous generation, and is not part of the theory of evolution.) It is worth noting that these first organisms are thought to be extremely simple in nature. The modern consensus among the scientific community is that they were single-celled.

I read in some Evolution Book that we started off as lemurs. So uh, yeah, I guess. TOODLES!!!!!

Answer 4

Evolution is an ongoing process which began with the first lifeforms.

AnswerThe first, most primitive life forms developed in the oceans more than a billion years ago. As soon as there was competition for food, access to sunlight or any other life-supporting resource, evolution began.

Answer 5

Evolution is a continuous process that has been occurring for billions of years, with the earliest evidence dating back to around 3.5 billion years ago. The exact moment "evolution started" is not easily pinpointed, as it is a gradual and ongoing phenomenon.

Answer 6

Evolution began 3 billion years ago, when the first life forms appeared on Earth.
