- Rating Newest Oldest. Best Answer: Most scientists believe that the first life forms were evolved in oceans that were BGA(blue green algae). Many believe that with these algae a simple organism named cyano bacteria was also evolved. Source(s): Shivansh · 5 years ago.

The origin of life on Earth: our collective history! The origin of life on Earth: our collective history! Life has existed on Earth for billions of years. The first organisms, which were microscopic, appeared in the ocean. They resembled the bacteria that we know today. The first algae and the first animals developed and gradually took over the seas.

List of Chinese inventions The early evolution of fish is unclear. It is thought that they evolved in the Cambrian Period (542 - 488 Ma). A primitive fish called Haikouichthys which is commonly recognis … ed as one of the 1st fish to evolve lived around 530 million years ago. 2 people found this useful.

- Around 530 million years ago, a wide variety of animals burst onto the evolutionary scene in an event known as the Cambrian explosion. In perhaps as few as 10 million years, marine animals evolved most of the basic body forms that we observe in modern groups.

Were Bacteria the First Forms of Life on Earth? Nevertheless, most scientists hold that the first organisms on Earth were much like bacteria of today. But several features of the biochemistry of life suggest that bacteria aren’t so ancient after all. In fact, in some respects, the cells of our own bodies tell us more about the evolution of life than bacteria do.

The origin of life on Earth: our collective history! Over time, very different living things have appeared, one after the other. For example, the development of a spinal column allowed certain animals to swim more efficiently, more than 400 million years ago. These first vertebrates were the fish. Little by little, certain fish developed lungs and feet and conquered dry land.

Evolution of insects Based on genome sequencing data, it is estimated that the class of insects originated on Earth about 480 million years ago, in the Ordovician, at about the same time terrestrial plants appeared. Insects evolved from a group of crustaceans. The first insects were land bound, but about 400 million years ago in the Devonian period one lineage of insects evolved flight, the first animals to do so. The oldest definitive insect fossil, Rhyniognatha hirsti, is estimated to be 407 to 396 million years old.

Earthâs Beginnings: The Origins of Life Clouds formed as the Earth began to cool, producing enormous volumes of rainwater that formed the oceans. For the next 1.3 billion years (3.8 to 2.5 billion years ago), the Archean Period, first life began to appear and the world’s landmasses began to form.Earth’s initial life forms were bacteria, which could survive in the highly toxic atmosphere that existed during this time.angea formed some 225 million years ago and would evolve into the seven continents we know today. Free oxygen began to build up around the middle of the Proterozoic Period — around 1.8 billion years ago — and made way for the emergence of life as we know it today.

How did a single cell evolve into a multi-celled organism? Originally Answered: Biology: How did the first multicellular organism evolve from single-celled organisms? According a recent hypothesis put forth byaccording Niklas and Newman . (Author information) multicellularity has evolved in several eukaryotic lineages leading to plants, fungi, and animals.

Organism The last universal common ancestor (LUCA) is the most recent organism from which all organisms now living on Earth descend. Thus it is the most recent common ancestor of all current life on Earth. The LUCA is estimated to have lived some 3.5 to 3.8 billion years ago (sometime in the Paleoarchean era).

What was Earth's first predator and when did it live? View image of The Ediacarans were some of the first complex organisms (Credit: Ryan Somma, CC by 2.0). In fact, there is evidence that predators existed before the anomalocaridids. Animals first began to grow hard shells and exoskeletons about 550 million years ago.

- The first homonids (animals from the same genus as people) evolved about 3 million years ago. Our species, Homo sapiens, evolved about 200,000 years ago.umans, chimpanzees, gorillas and orangutans share an earlie … r still common ancestor. These great apes and the gibbons of the Hylobatidae share an even earlier common ancestor. That is how evolution works, by common ancestry, the pattern of phylogeny tracing this out.

Oldest Fossil Evidence for Animals Found Fossils of microbe colonies currently are evidence of the first known life on Earth, dating back to 3.5 billion years ago. Thereafter came a long period with little major development. The new analysis aside, fossils of the earliest multicellular organisms had been dated to 565 million to 543 million years ago.

5.3: First Organic Molecules Some scientists speculate that RNA may have been the first organic molecule to evolve. In fact, they think that early life was based solely on RNA and that DNA and proteins evolved later. This is called the RNA world hypothesis.

What was the first life form on earth? Vote for this answer. It is estimated that the first life forms on earth were primitive, one-celled creatures that appeared about 3 billion years ago. That's pretty much all there was for about the next two billion years. Then suddenly those single celled organisms began to evolve into multicellular organisms.

What was the first living organism on Earth? Where did it come from? The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.

Origin of life If life evolved in the deep ocean, near a hydrothermal vent, it could have originated as early as 4 to 4.2 billion years ago. If, on the other hand, life originated at the surface of the planet, a common opinion is it could only have done so between 3.5 and 4 billion years ago. Lazcano and Miller (1994) suggest that the pace of molecular evolution was dictated by the rate of recirculating water through mid-ocean submarine vents.

How does life evolve? Things start out very small in our universe, and life is no exception. Today's Earth is home to a vast and varied population of living things, yet all life traces back more than 3 billion years to a lone, single-celled species. We call this organism the last universal common ancestor (LUCA). Some biologists believe LUCA evolved from simpler strands of nucleic acids.

Timeline: The evolution of life The first life may have developed in undersea alkaline vents, and was probably based on RNA rather than DNA. At some point far back in time, a common ancestor gave rise to two main groups of life: bacteria and archaea. How this happened, when, and in what order the different groups split, is still uncertain.

Early Evolution About 1.3 billion years ago the first eukaryote (a single cell organism with a complex inner structure) which contained many internal organelles such as mitochondria appeared, having evolved from the prokaryote. From the eukaryote, the multicellular metazoa (shown at left) evolved about 680 million years ago.
