This timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth

This timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. In biology, evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organization, from kingdoms to species, and individual organisms and molecules, such as DNA and proteins

The Carboniferous Period is also known as the Age of Amphibians. The plant life of the Carboniferous Period resembled modern tropical plants.

The Carboniferous Period is also known as the Age of Amphibians. It is the fifth of six geologic periods that together make up the Paleozoic Era. The Carboniferous Period is preceded by the Devonian Period and followed by the Permian Period. The climate of the Carboniferous Period was quite uniform (there were no distinct seasons) and it was more humid and tropical than our present-day climate.

Prehistoric Life: The Definitive Visual History of Life on Earth. This is a sumptuous and learned book. Many books discuss the issue of human evolution but few illustrate it with such high color photography. But it is also unreadable. It serves as a visually beautiful reference book, and a thick-volume to be thumbed through, read in parts, consulted, and used as a stimulus to the sense of wonder.

Life on Earth was his first program. This program is a short history of life on earth

In this unique book, David Attenborough has undertaken nothing less. Life on Earth was his first program. Nowadays, David Attenborough is such a household name, and his influence on nature documentaries is so widespread, that it made the experience of seeing the young Attenborough a bit jarring. He looks spry, even sprightly. This program is a short history of life on earth. Attenborough takes us from bacteria, to invertebrates, to plants, insects, fish, amphibians, reptiles, mammals, and finally to us.

Mesozoic Era and Triassic (251-200mya). oxygen levels rose again- life diversified again but from a different starting point, different directions on different continents.

What makes life on Earth so special? How do you explain its diversity? . But as biologists continue to study life on Earth, and as new species are discovered and more evidence comes in, the Tree of Life will continue to grow. At its center is LUCA, or the Last Universal Common Ancestor.

What makes life on Earth so special? How do you explain its diversity? And what exactly is it? . It's believed it was a single-celled organism born more than . billion years ago.

Early amphibians, animals that could live on land and in the water, appeared

Articles in Easy Understandable English for Learners. The oldest period of the earth’s history lasted from the beginnings four and a half billion years ago to about 600 million years ago. At first simple forms of one-celled life developed in the oceans. Later on bacteria and algae evolved. Early amphibians, animals that could live on land and in the water, appeared. The end of the era was the time of big forests and swamps.

Geological Ages, We can divide the history of life on Earth into six main stages . Amphibians and reptiles appeared. Reptiles were not common until the next era, the Mesozoic

Geological Ages, We can divide the history of life on Earth into six main stages: 1. 2. 3. Hadean Era: from the formation of the Earth about 4. 6 billion years ago until about 4 billion years ago. The Earth’s surface is constantly bombarded by large objects which repeatedly melt the whole surface, making life impossible. Note that it still had to originate somewhere. Reptiles were not common until the next era, the Mesozoic. Life evolved in the sea, but invaded the land during the late Paleozoic era.
