Researchers have concluded that earth-dwelling animals have a keen sense of color and that these water-repellent are remarkably resilient. Animals that are accustomed to living in open space on earth see a greater variety of colors than animals that are accustomed to forests.However, the evolutionary history – mainly the differences between invertebrates and invertebrates – has a profound effect on the color of the species. Invertebrates see a much shorter duration of light, compared to vertebrates.
Biology student Matt Murphy and assistant professor Erica Westerman recently published their findings in Proceedings of the Royal Society B. Their article, “The history of evolution limits the ability of species to match color sensitivity with natural light,” describes how the environment, evolution and, to some extent, genetics influence how and what colors an animal perceives.”Scientists have long assumed that animals’ vision has evolved to reflect the colors of light that are present in their environment,” said Westerman. “But this theory is hard to prove, and we still do not know much about animal theory. Collecting data on hundreds of species living in various habitats is a daunting task, especially considering that invertebrates and invertebrates use different types of cells in their eyes to convert light energy into responses. neuronal. “
The animal’s ability to detect visual information depends on wavelength and the intensity of light in a particular region. The abundance and sensitivity of the wavelength family of retina proteins, called opsins, dominate the animal’s visible light – from ultraviolet to distant red light.However, invertebrates and vertebrates use phylogenetically different opsins in their retina, and researchers have not yet determined whether these different opsins have an influence on what animals see, or how they adapt to their light environment.
Murphy and Westerman compiled opinion data for the 446 species of animals that took four phyla. One of these animals contained invertebrates – invertebrates, such as fish and humans. Some of these animals had invertebrates, invertebrates, such as insects, squid and jellyfish.Researchers have shown that although animals are accustomed to the environment, their ability to adapt to new environment may be impaired physically. Although vertebrates and invertebrates widely use the same cell type, opsins, in turn, form these cells differently. This difference in life – what biologists call ciliary opsins in vertebrates and rhabdomeric opsins in invertebrates – may explain why invertebrates are better at detecting short wavelengths, even when habitats have to choose vertebrate animals to see shorter lengths. they emit light waves.
However, the difference may be due to genetic mutations in vertebrates but not invertebrates, says Westerman. These changes may also limit the range of brightness in the vertebrate animals.”Our research answers some important questions,” says Murphy, “but it also creates additional questions that can help us to understand animals’ perceptions better. These are exciting questions. “
