Question

Which of the following is seen as evidence of choanoflagellates being sister to the rest of animals? Both early animals and c s move using flagella. O Choanoflagellates show signs of having primitive neurons, something only found in animals. The cells of choanoflagellates look almost indistinguishable from the collar cells of sponges. Several eary-diverging animal lineages have collar cells but they are not found in any other non-animal ineage Some genes of choanoflagellates contain domains that are clearly homologous to those of animals. Primitive single-celled animals have the same mode of reproduction as choanoflagellates.

Explanation / Answer

The correct answer seems to be the cells of choanoflagellates look almost indistinguishable from the collar cells of sponges as mentioned in the following statement.

There are striking physical resemblances between choanoflagellates and certainanimal cells, specifically the feeding cells of sponges, called choanocytes. Sponge choanocytes also have a flagellum and possess a collar of filaments for trapping food. Similar collars have been seen on several kinds of animals cells.
