• ancestor
  • New research shows that a burst of evolutionary innovation in the genes responsible for electrical communication among nerve cells in our brains occurred over 600 million years ago in a common ancestor of humans and the sea anemone. (psu.edu)
  • The research, led by Timothy Jegla, an assistant professor of biology at Penn State, shows that many of these genes, which when mutated in humans can lead to neurological disease, first evolved in the common ancestor of people and a group of animals called cnidarians, which includes jellyfish, coral, and sea anemones. (psu.edu)
  • It looks like the majority of these signaling systems first appear in the common ancestor that humans share with jellyfish and sea anemones. (psu.edu)
  • One of the exciting recent findings in evolutionary biology is that the nervous system might be much older than the ancestor of sea anemones and humans," Jegla said. (psu.edu)
  • We don't know how complex electrical signaling is in living comb jellies, but it probably wasn't very complex in our common ancestor," said Jegla. (psu.edu)
  • The team now is interested in figuring out what drove the burst of innovation in ion channels in our common ancestor with sea anemones. (psu.edu)
  • For our purposes in this article, a grouping of pigments based on similar features inherited from a common ancestor. (advancedaquarist.com)
  • Many of these genes, which when mutated in humans can lead to neurological disease, first evolved in the common ancestor of people and a group of animals called cnidarians, which includes jellyfish, coral, and sea anemones. (dailygalaxy.com)
  • Nematostella
  • The starlet sea anemone (Nematostella vectensis) is a species of small sea anemone in the family Edwardsiidae native to the east coast of the United States, with introduced populations along the coast of southeast England and the west coast of the United States. (wikipedia.org)
  • Jegla
  • Humans and sea anemones went their separate ways evolutionarily speaking roughly 600 million years ago," said Jegla, "so we know that the mechanisms we use to generate impulses in our neurons must be at least that old. (psu.edu)
  • If our hypothesis turns out to be correct, we may be able to gain some important insights into how nerve cells and circuits evolved by studying sea anemones,' said Jegla. (dailygalaxy.com)
  • basal
  • In this process, part of the basal disc of the sea anemone gets detached as the anemone moves over the substrate, and this piece is able to grow into a new individual. (wikipedia.org)
  • Latin
  • The neurotoxin was named BgK, with the Bg representing the Latin taxonomy (Bunodosoma granulifera) of the specific sea anemone from which the toxin was found, and the K standing for the chemical symbol for potassium owing to its observed effects on K+ channels. (wikipedia.org)
  • found
  • It is one of the most common anemones found on reefs in the Caribbean Sea. (wikipedia.org)
  • BgK is a neurotoxin found within secretions of the sea anemone Bunodosoma granulifera which blocks voltage-gated potassium channels, thus inhibiting neuronal repolarization. (wikipedia.org)
  • BgK can be found in the mucus of the Bunodosoma granulifera, a common sea anemone found along the coasts of Cuba. (wikipedia.org)
  • The binding sites of the toxin between Kv1.1, Kv1.2, and Kv1.3 were found to include three common amino acid residues: Lys-25, Tyr-26, and Ser-23. (wikipedia.org)
  • The anemone may also be found in regions of variable salinity such as estuaries. (wikipedia.org)
  • The shrimp species Periclimenes aegylios may be found living symbiotically with this sea anemone. (wikipedia.org)
  • Indeed, no bacterial OTU was ubiquitously found in all anemones samples. (peerj.com)
  • California
  • The anemone is known to carpet the bottom of some areas, like Campbell River in British Columbia, and Monterey Bay in California. (wikipedia.org)
  • algae
  • The anemone is analogous to the supervisor who supports the pet project of a subordinate, while the algae are analogous to the subordinate who nurtures the pet project. (chacocanyon.com)
  • corals
  • Corynactis californica is a bright red colonial anthozoan similar to sea anemones and scleractinian stony corals. (wikipedia.org)
  • gene
  • Analysis of expressed sequence tags and the whole genome have shown a remarkable degree of similarity in the gene sequence conservation and complexity between the sea anemone and vertebrates. (wikipedia.org)
  • By comparing sequences of the V1-V3 hypervariable regions of the bacterial 16S rRNA gene, we revealed that anemones host a complex and diverse microbial community. (peerj.com)
  • Scientists
  • PhysOrg.com) -- Scientists studying the behavioural traits of the common sea anemone have discovered that fortune favours the brave when it comes to fighting and setting territorial disputes. (phys.org)
  • When the sea anemone genome was sequenced in 2007, scientists discovered that it was very similar to the human genome, both in terms of the number of genes (roughly 20,000) and its organization , explains Heather Marlow, a specialist in developmental biology in the (Epi)genomics of Animal Development Unit at the Institut Pasteur and the main author of this study.
