Is bigger always better, or will the tiny inherit the Earth?

As I scuba dive in Oslob Bay off Cebu Island in the Philippines, I see a tiny shadow dart over the surface of the spherical coral block – a minute fish, a goby of the genus Eviota, among the smallest vertebrates in existence, only about a centimetre long and less than 1/10th of a gramme […]

How big is the blue whale? Watch to see

The blue whale (scientific name: Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). Up to 31 meters (102 feet) in length and 190 tonnes (210 short tons) in weight, it is the largest extant animal and also is the heaviest known to have existed. But it’s hard to conceptualize how big […]

How seeing snakes in the grass helped primates to evolve

Evolution has favoured the modification and expansion of primate vision. Compared with other mammals, primates have, for example, greater depth perception from having forward-facing eyes with extensively overlapping visual fields, sharper visual acuity, more areas in the brain that are involved with vision, and, in some primates, trichromatic colour vision, which enables them to distinguish […]

Is Evolution “just a theory”?

I recently saw a question on Quora and it was like that: “why is it called the ‘theory of evolution’ but the ‘law of gravity’?” This question is strongly related to a common misconception about evolution: “it is just a theory” – creationists always say “evolution is just a theory”.

Earth without Moon – what would it be like?

The Moon is the Earth’s only natural satellite. It is also the fifth-largest natural satellite in the Solar System and the largest among planetary satellites relative to the size of the planet that it orbits. It formed about 4.51 billion years ago from the debris left over after a giant impact between Earth and a […]

Dinosaurs were already doomed as the frequency of Asteroid Impacts increased 290 million years ago

By studying lunar craters, scientists have discovered that the asteroid impacts became more frequent about 290 million years ago. So was just a matter of time for dinosaurs to becoming extinct.

What If Earth’s History Compressed Into The Year of 2018

What if the Earth’s history (our planet’s age is approximately 4.54 billion years), compressed into just one year, let’s say the year of 2018? @YearOnEarth just did that. At midnight on the 31st of December 2017, Chris Jennings started a little project for the incoming year: tweeting the entirety of the geological history of the […]

Proof of life: how would we recognise an alien if we saw one?

What would convince you that aliens existed? The question came up recently at a conference on astrobiology, held at Stanford University in California. Several ideas were tossed around – unusual gases in a planet’s atmosphere, strange heat gradients on its surface. But none felt persuasive. Finally, one scientist offered the solution: a photograph. There was […]
