The First Birds Birds evolved from feathered dinosaurs – modern birds are essentially Velociraptors with beaks instead of snouts and wings instead of arms. The most famous early bird, Archaeopteryx, lived 150 million years ago. But in recent years slightly older fossils, such as Xiaotingia and Aurornis, have been found in China.

Flowers Flower This may sound strange, but flowers are a recent invention. There have been land plants for 465 million years, yet there were no flowers for over two-thirds of that time. Flowering plants only appeared in the middle of the dinosaur era. The equally-familiar grasses appeared even more recently. The oldest fossil grasses are just 70 million years old, although grass may have evolved a bit earlier than that.

Death Of The Dinosaurs Boom, you're extinct. 65 million years ago, a huge chunk of rock from outer space smashed into what is now Mexico. The explosion was devastating, but the longer-term effects were worse. Dust was thrown into the upper atmosphere and blocked out sunlight, and in the ensuing cold and darkness Earth suffered its fifth and last mass extinction. The dinosaurs were the most famous casualties, but pterosaurs and giant marine reptiles were also wiped out.

Living In The Trees Almost immediately after the dinosaurs were wiped out, mammals evolved the ability to nourish their young inside their wombs using a placenta, just like modern humans. Soon, some of these early placental mammals evolved into the first primates. They would ultimately give rise to monkeys, apes and humans. But the first ones were small creatures. The oldest known primate skeleton is of a species called Archicebus achilles, which weighed no more than 30 grams. They lived in the hot and humid rainforests of Asia.

Supercharged Plants Plants have been busily harnessing sunlight to make sugar for hundreds of millions of years – a process called photosynthesis. But fairly recently, some plants have found a better way to do it. C4 photosynthesis is far more efficient than normal photosynthesis, allowing C4 plants to cope with harsh conditions. Today scientists are trying to engineer rice to use C4 photosynthesis, to help feed the growing population.

Road To Humanity The first apes appeared in Africa around 25 million years ago. Then at some point, the group split into the ancestors of modern humans and the ancestors of modern apes. It's hard to say exactly when, but thanks to modern genetics and a host of fossil discoveries, we have a rough idea. The oldest known hominid was Sahelanthropus tchadensis, which lived about 7 million years ago.

The Thinking Ape Our species, Homo sapiens, is ridiculously young. We have only existed for a fifth of a million years. In that time we have expanded from our African birthplace to reach every continent, and even outer space. Our activities have precipitated the sixth mass extinction and unleashed the fastest episode of climate change in Earth's history. Yet we are also the only species that has ever managed to piece together the history of Earth.

Earthquake in nepal Magh (January- February) earthquake, Known as Great Nepal-Bihar Earthquake, struck the Kingdom of Nepal and its surrounding areas around 2 pm on the January 16. The magnitude of the earthquake was 8.4 on the Richter scale. Casualty figures were highest for any recorded earthquake in the history of Nepal

hat is Computer : Computer is an electronic device that is designed to work with Information. The term computer is derived from the Latin term ‘computare’, this means to calculate or programmable machine. Computer can not do anything without a Program. It represents the decimal numbers through a string of binary digits. The Word 'Computer' usually refers to the Center Processor Unit plus Internal memory.

Charles Babbage is called the "Grand Father" of the computer. The First mechanical computer designed by Charles Babbage was called Analytical Engine. It uses read-only memory in the form of punch cards

1255 AD The first recorded earthquake in history of Nepal took place on June 7, 1255 AD. One-third of the total population of Kathmandu were killed including Abahya Malla , the King of Kathmandu valley. Numerous buildings and temples of the valley were entirely destroyed while many of them were severely damaged, the magnitude of the earthquake is said to be around 7.7 in Richter scale

omputer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.

1260 AD Next recorded big earthquake after 1255 AD was during the reign of King Jayadev Malla. Many buildings and temples collapsed and many more were severely damaged. Although the exact number of fatalities cannot be confirmed, it said there was heavy loss of life because of the earthquake and the subsequent epidemic and famine.

1408AD The month August or September of this year saw another major earthquake hit the valley of Kathmandu and the surrounding areas, during the reign of king Shyam Singh. The temple of Rato Matchendranath was completely destroyed while many other temples and buildings collapsed and were damaged. Cracks on land appeared in many places. There was a heavy loss of lives and livestock.

Digital Computer Definition The basic components of a modern digital computer are: Input Device, Output Device, Central Processor Unit (CPU), mass storage device and memory. A Typical modern computer uses LSI Chips. Four Functions about computer are

1681 AD Either on the month of December or January, during the reign King Sri Niwas Malla, another major earthquake hit Nepal and Kathmandu valley. Although very little information is available on this particular earthquake, there was heavy loss lives as well as many buildings, including temples, were either damaged or destroyed.

1767 AD In months of June and July another significant earthquake hit Nepal. Twenty one shocks and aftershocks of this particular earthquake is said to have occurred in a span of twenty four hours. No written or verbal records survive to indicate any human casualty or the magnitude of sufferings and damages caused.

1810 AD During the reign of King Girban Yudha Bikram Shah in the months of May or June twenty one shocks of earthquakes in total were felt in Nepal. Although the loss in human lives and cattle were limited, many houses, building and some temples were either destroyed or damaged.
