150 million years ago, during the Triassic period, birds appeared right after dinosaurs. There are 10,000 species of birds that have been identified. the Ostrich is the largest known birth in earth.
130 million years ago, during the cretaceous period, flowers and bees came to existence. Bees are divided into three groups;queen, workers and drones. When the queen dies workers decide in another one in order to be guided to pass pollen around and create new flowers.
243 million years ago, during the Triassic period, reptile dinosaurs appeared.There is four main groups of reptiles. They consist of scaly skin and cold blooded soul.
200 million years ago, during the age of mammals, within 10 million years of the dinosaurs, mammals originated. There is about 5,000 mammal species in existence. ALL mammals nature thier young with milk.
367 million years ago, tetrapods appeared because of the specific aquatic ancestor of tetrapods. Their sizes vary a lot going from 8 millimeters to 30 millimeters long. They have various adaptations of skeleton and muscles that help them live a proper life.
400 million years ago, during the devonian period, insect fly evolved from a group of crustaceans. More than 120,000 species of flies have been found worldwide. Most of them living an average of 21 days
425 million years ago, armored jawless ostracoderms roamed and them thats is when sharks came in. Sharks have skeletons made up of cartilage. They breathe through a series of 5-7 gill slits.
542 million years ago,corals appeared in the Cambrian period.Corals are marine invertebrates in the classes of phylum cnidaria and anthozoa. The group includes reef builders inhabiting tropical oceans and calcium carbonate.
510 million years ago,in the cambrian, fishes appeared for first time. They were long established before dinosaurs roamed Earth. About 15,00 species of fishes have been known as unidentified.
541 million years ago, cambrian explosion the most major number of animals were created. Such as jellyfish, mira pods, crustaceans, arachnids, echinoderms, worms, molluscs, and arthropods.
1.5 billion years ago, protozoa were formed. They Are descendants from the early forms of life . They mineralize nutrients making them available for use by plants and other nutrients.
1.1 billion years ago, a limb of genealogical tree branched away from plants forming or adding to the evolution of sponges and fungi.
2.7 billion years ago cyanobacteria became the first microbes to produce oxygen by atmospheric oxygen. Although many people don't know, atmospheric oxygen is bigger need than food that we have. It is essential for higher forms of life to form.
2 billion years ago, a symbolic association of prokaryotes evolved from bacteria, evolving from bacteria in living cells which is process of eukaryotes. These cells are larger than prokaryotic cells and have a real nucleus, membrane, organelles, and chromosomes. this nucleus houses the cells DNA.
3 billion years ago, single-celled water creatures(Prokaryotes) begin their 2-billion year process of evolving into more complex forms of life.Prokaryotes do not have separated organelle or nucleus bound inside a membrane within a cell. They were discovered in micro-fossils and in large fossilized structures.
3 billion years ago, photosynthesis evolved from anaerobes living without oxygen being poisoned when blue-green algae made photosynthesis to start exhaling oxygen. In photosynthesis, all the energy absorbed converts into oxygen. Then oxygen is released as a by-product.
3.5 years ago, fossilized bacteria have been found in rock in Africa. Some food, are purposely created by adding some bacteria; commonly in snacks.Sometimes the more bacteria you have, the less obesity that is created.
4.6 billion years ago, a galaxy formed called the Milky Way in which one of the stars was our sun. This star wonders around the red giant region, developing distinct layers which then create a carbon-oxygen core.In the sun, temperature never reaches the 600 million degrees which are required for carbon burning
4 billion years ago, Earth condensed into a sphere with inner core; extremely dense and hot.Earth is the third planet from the sun, known as the only planet to support an atmosphere with free oxygen, and with oceans of liquid water on surface. Our planet is always revolving around the sun 67,000 miles per hour.
4.5 billion years ago, The Theia Impact occured and debris from the collision formed what we now know as the moon. Both sides of the moon see the same amount of light from the sun, although Earth can only see one side of the moon. Yearly, the moon is moving apart from earth approximately 38 cm.
