Marine species relocating to poles as oceans heat up

Researchers studying data collected over a century on more than 300 marine animals, birds, and plants have concluded that many of these species are shifting towards the poles as the world’s oceans continue to heat rapidly. The team noticed that the wildlife showed a “general pattern” of shifting towards the poles while their numbers have reduced near the equator. More on the Independent.

Possible ancestor of all animals identified in Australian fossils

The 555 million year old fossils found in Australia seem to point to a common ancestor of all animals. These fossils are in the shape of rice grains, made up of small layers of microfossils. They are few millimetres in length and were deduced to be worms with a mouth and anus, a feature called bilateralism. The worm is now thought to be one of the earliest species to exhibit bilateralism and thus could be the ancestor of all animals. More on Evolution News.

Antarctic glacier retreated 5 km in 22 years

A glacier in Antarctica called the Denman glacier has retreated at an astonishing speed. The glacier has retreated by nearly 5 km in the past 22 years, losing nearly 250 billion tons of ice. As ice retreats, thicker and thicker ice melts, releasing a huge amount of freshwater into the ocean and changing the ocean permanently. The findings reveal the alarming pace of the changing ecosystem of Antarctica. More on Science Alert.
