Timeline of Photosynthesis on Earth
| 4.6 billion years ago | Earth forms |
|---|---|
| 3.4 billion years ago | First photosynthetic bacteria appear |
| 2.7 billion years ago | Cyanobacteria become the first oxygen producers |
| 2.4 – 2.3 billion years ago | Earliest evidence (from rocks) that oxygen was in the atmosphere |

Q. Which animal walked across the area first?
1. Ichthyostega. Ichthyostega devonian dinosaur, dinosaur park. The first creature that most scientists consider to have walked on land is today known as Ichthyostega.
Q. How many individuals animals were here?
Answer. Answer: The approach accurately predicted the number of species in several well-studied groups such as mammals, fishes and birds, providing confidence in the method.” And the number came out as 8.7 million – plus or minus about a million.
Q. How many animals are there in the world in 2020?
The natural world contains about 8.7 million species, according to a new estimate described by scientists as the most accurate ever.

Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours. This is nearly 1,000 times the “natural” or “background” rate and, say many biologists, is greater than anything the world has experienced since the vanishing of the dinosaurs nearly 65m years ago.

Q. How many animals are dying because of global warming?
Climate change is accelerating the sixth extinction World biodiversity has declined alarmingly in half a century: more than 25,000 species, almost a third of those known, are in danger of disappearing. Climate change will be responsible for 8% of these.
Q. Will animals go extinct?
These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. But if the upper estimate of species numbers is true – that there are 100 million different species co-existing with us on our planet – then between 10,000 and 100,000 species are becoming extinct each year.
