Now Maja Adamska of Uni Research Sars Centre feels even more convinced that we all have a little bit of sponge in us.
Sponges are ancient animals that have changed little in the past 600 million years. They live a rather anonymous life on the ocean floor as the simplest, and possibly also the oldest, multicellular organisms on Earth.
There is no doubt that millions of years of evolution have brought forth far more spectacular and advanced species, while sponges have largely remained unchanged.
Nevertheless, Adamska and other scientists are quite convinced that advanced species such as humans have evolved precisely from the primitive form of life of the sponge.
The same body plan
Many human genes are very similar to those of the sponge; a direct relationship can be seen between many of them. But that’s not all.
In a new study headed by Adamska, the main conclusion is that we humans have evolved from the same body plan as sponges.
