I stumbled upon an amazing web page showing what did ancient Earth look like. On “Dinosaur Pictures and Facts” web page (dinosaurpictures.org), there’s also an interactive animation. On this page, you can either select the years (i.e. 600 million years ago) or jump to a particular event (i.e. first multicellular life) and see how ancient Earth did look like then. You can also remove the clouds and stop the Earth’s rotation if you want to.

Are we alone in the Universe? Or any other life forms exist out there? A new study, published on the Proceedings of the National Academy of Sciences of the United States of America (PNAS)Notes 1 suggests that the life emerged so early on Earth – it should be widespread. In other words, the Universe should be filled with life.
The story goes back to 1982. 35 years ago, UCLA Scholar and Pioneer in Study of the Evolution of Life, J. William Schopf collected 3.465-billion-year-old fossils from the Apex Chert in western Australia, and interpreted them as early life. When he described the fossils in the journal Science in 1993, critics had argued that they were not early lifeforms – they were just odd minerals that only looked like biological specimens.

According to the scientists who drilled into the Chicxulub crater buried underneath the Yucatán Peninsula and the Gulf of Mexico, the asteroid hit the “worst possible place”. They summarized their findings so far in a BBC Two documentary titled “The Day The Dinosaurs Died“. The documentary presented by professors Alice Roberts and Ben Garod.

Here are the top six largest fish species (within around 33,100 described species).
But, first of all, what is a fish? At first, it looks like an easy question, but in fact, it is not. There are a wide range of animals we call “fish”, so it is not easy to define what makes a fish “a fish”. A general description: “a fish is any member of a paraphyletic group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits” (Wikipedia).

All fishes have a brain protected by a braincase, and an obvious head region with eyes, teeth, and other sensory organs.
People believe many things which are actually not true. Here are the top ten misconceptions about Earth.

In the past, there were five major extinction event (a widespread and rapid decrease in the biodiversity on Earth), and a lot of minor ones. Now, we are in the middle of the sixth one, called “Holocene extinction event”. And the cause is… guess what? Humans.
According to the WWF’s (World Wildlife Fund) new Living Planet Report (2016), now we are in the middle of the biggest mass extinction on Earth, since the dinosaurs, which was around 65 million years ago. And the world set to lose two-thirds of its wildlife by as close as 2020.

Like crocodiles, snakes also suffer from a prevalence of “big fish” stories and over-exaggeration in the internet era. In fact, it is very difficult to measure how large actually a snake is, especially if it’s really big. So, how big are the largest snakes actually?
