Exempel på hur man kan använda MULTICELLULARITY i en mening

• They are structurally diverse: most groups of chlorophytes are unicellular, such as the earliest-diverging prasinophytes, but in two major classes (Chlorophyceae and Ulvophyceae) there is an evolutionary trend toward various types of complex colonies and even multicellularity.
• Members of the order are Protista of great theoretical interest in biology because they have aspects of both unicellularity and multicellularity.
• Astrobiologists Dirk Schulze-Makuch and William Bains, reviewing the history of life on Earth, including convergent evolution, concluded that transitions such as oxygenic photosynthesis, the eukaryotic cell, multicellularity, and tool-using intelligence are likely to occur on any Earth-like planet given enough time.
• The position of nucleariids, unicellular free-living phagotrophic amoebae, as the earliest lineage of Holomycota suggests that animals and fungi independently acquired complex multicellularity from a common unicellular ancestor and that the osmotrophic lifestyle (one of the fungal hallmarks) was originated later in the divergence of this eukaryotic lineage.
• Volvox carteri is a significant model organism for research into the evolution of multicellularity and organismal complexity, largely due to its simple differentiation into two cell types, versatility in controlled laboratory environments, and natural abundance.
• His group also identified a paralog of DTD1 in animals known as Animalia-specific-tRNA Deacylase (ATD), which plays a crucial role in protecting animals from mistranslation associated with oxidative stress and its implications in the evolution of multicellularity in Animalia.
• More recently, Schaap and her team showed that the molecular pathway for multicellular development in dictyostelids had evolved from an ancestral encystment pathway present in single-celled amoebae, thus contributing to elucidating the molecular basis for the evolution of multicellularity.
• Though unproven, some virologists posit that viruses may have played an important role in major evolutionary events, including the emergence of a DNA genome from an RNA world, divergence from LUCA to the three domains of life, archaea, bacteria, and eukarya, and development of multicellularity.
• This 8- or 16-cell colony represents one of the first steps to true multicellularity, presumed to have evolved from the unicellular common ancestor earlier than other Volvocine algae.
• One helkesid genus, Guttulinopsis, represents an independent lineage in which aggregative multicellularity has evolved to generate "fungi-like" fruiting bodies called sorocarps, similarly to slime moulds such as Dictyostelium.
