"To my knowledge, aside from circumstantial evidence presented in the literature (Levin, 2019), the meaning of which is debated among astrobiologists, this is the first professional report of direct evidence of identifiable life forms beyond the confines of Earth"- Quote By William S. Romoser, Ph.D., Professor Emeritus, Ohio University, At hens, Ohio.
Ohio University Emeritus Professor William Romoser has analyzed photos from NASA’s various Mars rovers, mostly from the rover Curiosity, and found insect/arthropod- and reptile-like organisms (both as fossils and living creatures) in the images. “There has been and still is life on Mars,” said Professor Romoser, who was an entomology professor at Ohio University for 45 years and co-founded its Tropical Disease Institute, also spent nearly 20 years as a visiting vector-borne disease researcher at the U.S. Army Medical Research Institute of Infectious Diseases. He presented the findings November 19, 2019 at the National Meeting of the Entomological Society of America in St. Louis, Missouri.
According to his finding There is no doubt that there is life on other Planets, and now provably Mars.
Does Insect/Arthropod Biodiversity Extend Beyond Earth? Written by William S. Romoser, Ph.D., Professor Emeritus, Ohio University
There is ample evidence to answer the question posed by the title in the affirmative. For several years, I have been engaged in study of the NASA-JPL photographs transmitted to Earth from the surface vehicles sent to explore Mars, Curiosity Rover in particular. These photos are available to the public via the internet.
In this poster, I present and discuss numerous examples of insect/arthropod-like forms (fossil & living) found in Mars rover photos. Examples include insect-like forms displaying apparent diversity, clearly recognizable insect/arthropod anatomical features, and flight. Evidence of a fossil reptile-like (serpentine) form as well as apparent living reptile-like forms preying on insect-like forms is also presented. Each example is documented. These findings provide a compelling basis for further study and raise many important questions.
Interest in the possibility of life on Mars (Dass, 2017), a desire to find useful resources for technology, possible colonization (Levine & Schild, 2010), and a great sense of adventure has stimulated research and development in regard to reaching Mars. Accordingly, earlier projects involved placing spacecraft in orbit around Mars to send back photos of the Martian surface. More recently, unmanned vehicles have been sent to land on the Martian surface to relay images of the surroundings back to Earth and to collect information about the surface and from shallow drill holes. Onboard instrumentation has tested for evidence of past and present life via indicators of organic activity, namely “biosignatures” (Cady et al., 2004; Levin, 2019).
Another approach has been to seek out and analyze the structural, physiological, and biochemical adaptations of Terran organisms that are able to live under extreme environmental conditions, that is “extremophiles” (Merino et al. 2019, ). This approach has been almost entirely focused on microbes, though metazoans, e.g. tardigrades, and some insects and reptiles have been found in extreme habitats on Earth.
My intent in this poster is to present evidence of fossil and living insect- and reptile-like forms on Mars. A few of many findings are included and additional results will be published soon. Repeatability and corroboration are among the hallmarks of the scientific method and as it is likely that at least some NASA/JPL personnel are acquainted with Martian insect- and reptile-like creatures, the research reported here can reasonably be viewed as replicative and corroborative. The arthropod body plan with repeating body segments, a typically tough, resilient exoskeleton, along with a high degree of physiological and biochemical adaptability are among the characteristics that make members of this group prime candidates for thriving under harsh environmental conditions. Likewise Terran reptiles are commonly found in extreme environments.
Based on preliminary examination of Mars rover photographs, I formulated the following broad, hypothesis as the basis for the research reported here: There are fossilized and living forms on Mars, including insect/arthropod- and reptile-like form.
Plate 1. Insect-like forms, most of which display
three body regions (head, thorax, & abdomen)
and wings that articulate with the thorax. The
fourth image from the top on the left side has
only a head and trunk and could be an immature
insect-like form or another kind of arthropod.
MATERIALS & METHODS
The NASA-JPL images relayed to Earth by land-based vehicles (“rovers”), sent to Mars via spacecraft are available to the public on the internet. This database of photos, both raw images and compiled panoramic mosaics, that has been collected over many years by several different missions has been used in this study, mostly from Curiosity rover (NASA/JPL). Individual images were carefully studied while varying photographic parameters such as brightness, contrast, saturation, inversion, and so on. No content was added, or removed.
The following criteria were useful in identifying life forms: dramatic departure from the surroundings, clarity of form, body symmetry, segmentation of body parts, repeating form, skeletal remains, and observation of forms in close proximity to one another. Particular postures, evidence of motion, flight, apparent interaction as suggested by relative positions, and shiny eyes were taken to be consistent with the presence of living forms. Once a clear image of a given form was identified and described, it
was useful in facilitating recognition of other less clear, but none-the-less valid, images of the same basic form.
The descriptions and interpretations of images are somewhat tentative, and may well change with more study and as knowledge of Martian fauna increases. I encourage you to check my findings for yourself. The URLs of the photos used will be listed on my website, scienceofentomology.com and in formal publication of this material in the future.
Plate 2. Various anatomical structures seen in different photos. A - E and probably F are “beelike”, but not necessarily the same type. (A & B) A specimen whose head appears to have turned in the direction of the camera (based on the scale provided in the photo from which this was extracted, this individual is estimated to be approximately 20 inches long). (C) Abdomen of specimen from “a.” (D) Individual on ground with head facing left with head & thorax visible. (E) Individual flying with legs evident and, though in flight, somewhat comparable to the specimen in D; Compound eyes and hindlegs labeled in two positions since in motion. Relative to D & E, the locations, shapes, sizes, and appearance of the legs suggest that the forelgs, with putative distal chelate structures, are grasping; the midlegs, digging; and the hindlegs, jumping & running. (F) Specimen on ground with wing(s) toward the right. Longitudinal veins, cross veins, and wing cells evident. (G) Part of wing of specimen apparently caught on the rover; inset: enlarged portion of wing. Longitudinal veins, cross veins, and cells are evident.
It appears that the “Red Planet” enjoys a surprising abundance of higher life forms. An exoskeleton and jointed appendages are sufficient to establish identification as an arthropod (Romoser & Stoffolano, 1995).
Three body regions, a single pair of antennae, and six legs are traditionally sufficient to establish identification as “insect” on Earth. These characteristics should likewise be valid to identify an organism on Mars as insect-like. On these bases arthropodan insect-like, forms can be seen in the Mars rover photos.
Many insect-like creatures and putative diversity were observed (Plate 1). The most common insect-like forms are robust and loosely resemble bumble bees or carpenter bees on Earth. For convenience, with no taxon necessarily implied, I’ll refer to these creatures as “bees” from this point on. The “bees” appear to vary in size and type. Several characteristic insect/arthropod anatomical features were identifiable (Plate 2), not all on the same individual, but as a mosaic among individuals.
Distinct flight behavior was evident in many images, e.g. Plates 3 & 4. In one case observed, the flight manuever was impressive with the individual “bee” plunging straight down the side of a cliff and leveling off just before hitting the ground (Plate 4).
The insect-like fauna observed appeared to be sheltering/nesting in caves (Plate 3E), in burrows beneath the surface, and in specialized structures.
Possible predation of the insect-like types by reptile-like creatures (Plate 5) and putative insect-like (“bee”) and reptile-like fossils were seen (Plate 5).
The descriptions/interpretation of insect- and reptile-like creatures described here are tentative and may be changed in the future as knowledge of putative Martian Fauna increases with further study.
