After a neat video on Tardigrades, we discuss them
Check this video by Neil DeGrasse Tyson on these cute little buggers https://www.youtube.com/shorts/qcje-Y63PpU?feature=share Conversation with Perplexity Tell me about the DNA and genetic relationships with tardigrades. Tardigrades have several interesting genetic and DNA-related characteristics: Genome Size and Structure Tardigrade genomes vary considerably in size, ranging from about 75 to 800 megabase pairs of DNA . For example, Hypsibius exemplaris (formerly Hypsibius dujardini) has a compact genome of about 100 megabase pairs . This is relatively small compared to many other animals. Evolutionary Relationships Although tardigrades superficially resemble arthropods like insects and spiders, genetic evidence suggests they are more closely related to nematodes (roundworms) . Molecular analyses have confirmed tardigrades as a sister group to arthropods. Unique Genes Tardigrades possess several unique gene families associate...
