Which organism was used to re-evaluate its position in the tree of life using the recent technology?

Fungi

Explanation:

Fungi is a eukaryotic organism that is re-evaluating its position in  the tree of life.

Fungi are closely related to the animal kingdom in comparison to the plant kingdom. Because of the presence of the chitin in their cell walls, fungi is different from plant, bacteria, and protists. But fungi have cell wall while animal cells do not contain cell wall, so not classified as animals.

So, fungi is re-evaluating its position in  the tree of life and in present there is a individual kingdom for fungi.
