Discovery: Initial Branched Division in the Evolutionary Family Tree Identified by Scientists
In a significant breakthrough for the field of evolutionary biology, a team led by Leonid Moroz has conducted chromosome analysis on comb jellies, revealing these fascinating creatures as the first animal group to have diverged from our common ancestor.
For decades, scientists have debated the identity of the sister ancestor to all other animals. The question, long unanswered, has now been settled. The comb jelly, with its unique and captivating characteristics, has been found to be the first to branch off, making it the sister to all other animals.
The key to this discovery lies in the placement of genes on chromosomes. Using new chromosomal analysis techniques, the research group was able to trace the common ancestor of all animals on Earth. The first split resulting from this ancient division produced two creatures: the ancestor of almost all animals, and a "sister" ancestor to one group of modern-day animals - the comb jellies.
This discovery provides new insights into the history of animal evolution. The comb jelly, now established as the most genetically isolated animal, offers a unique perspective on the mechanisms that powered animal evolution. Scientists are eager to delve deeper into this new knowledge, hoping to uncover more about the intricate workings of life's diversification.
