samples were submitted to the Medical Research Institute of the Ministry of Health in Colombo. The rocks were sent to the University of Cardiff in Wales for analysis, where Chandra Wickramasinghe's team analyzed them and claimed that they contained extraterrestrial diatoms. From January to March 2013, five papers were published in the fringe Journal of Cosmology outlining various results from teams in the United Kingdom, United States and Germany. However, independent experts in meteoritics stated that the object analyzed by Wickramasinghe's team was of terrestrial origin, a fulgurite created by lightning strikes on Earth. Experts in diatoms complemented the statement, saying that the organisms found in the rock represented a wide range of extant terrestrial taxa, confirming their earthly origin. Wickramasinghe and collaborators responded, using X-ray diffraction, oxygen isotope analysis, and scanning electron microscope observations, in a March 2013 paper asserting that the rocks they found were indeed meteorites, instead of being created by lightning strikes on Earth as stated by scientists from the University of Peradeniya. However, these claims were also criticised again not providing evidence that the rocks were actually meteorites. Cephalopod alien origin In 2018, Wickramasinghe and over 30 other authors published a paper in Progress in Biophysics and Molecular Biology entitled "Cause of Cambrian Explosion - Terrestrial or Cosmic?" which argued in favour of panspermia as the origin of the Cambrian explosion, and posited that cephalopods are alien lifeforms that originated from frozen eggs that were transported to earth via meteor. The claims gained widespread press coverage. Virologist Karin Mölling, in a companion commentary published in the same journal, stated that the claims "cannot be taken seriously". Participation in the creation-evolution debate Wickramasinghe and his mentor Fred Hoyle have also used their data to argue in favor of cosmic ancestry, and against the idea of life emerging from inanimate objects by abiogenesis. Wickramasinghe attempts to present scientific evidence to support the notion of cosmic ancestry and "the possibility of high intelligence in the Universe and of many increasing levels of intelligence converging toward a God as an ideal limit." During the 1981 scientific creationist trial in Arkansas, Wickramasinghe was the only scientist testifying for the defense, which in turn was supporting creationism. In addition, he wrote that the Archaeopteryx fossil finding is a forgery, a charge that the scientific community considers an "absurd" and "ignorant" statement.
