Even with sequence-based analyses, the biases can also be corrected for: Whelan et al. (2017), using such an approach, strongly rejects the hypothesis that sponges are the sister group to all other extant animals and establishes the placement of Ctenophora as the sister group to all other animals, and disagreement with Simion et al.

[2] The species may have an extremely long lifespan, with estimates of up to 15,000 years. [3]
