Engineers, microbiologists and biochemists continually look to spiders, their webs and their venom for inspiration to develop new products and compounds.īizarre body ornamentation and bright, metallic colors are common in many Neotropical spider families, including jumping spider (Salticidae) and orb-weavers (Araneidae), making them attractive subjects for visiting photographers. Despite their well-deserved reputation for cannibalism, some species are now known to be semi social or even colonial. Brazilian wandering spiders ( Phoneutria), six-eyed sand spiders ( Sicarius) and Australian funnel-web spiders ( Atrax) provide an endless supply of internet clickbait. Crab spiders (Thomisidae) amaze us with their floral mimicries.

Black widows ( Latrodectus) dispense both excuses for unexplained, persistent skin ulcers as well as easy metaphors for crime fiction writers. Tarantulas often show vividly contrasting or metallic colors (mostly blues and violets), females are usually long-lived (to ~20 years), and some species exhibit remarkable physical abilities and learning behaviors. This is a fascinating group of arthropod predators (although one remarkable Mesoamerican jumping spider species – Bagheera kiplingii - is a sometime vegan) that includes some incredibly beautiful animals. (and fungus are more related to us then plants.)Īnd that's why we have multiresistant strains of bacteria and why they're so much more prevalent in hospitals.This uneasy relationship with them does not, however, negatively bias my opinions about spiders when they’re not skating over my forearm or neck. Speaking of mushrooms, we are more closely related to fungus then to plants. So what is the lesson to be learned here? The mascot of genderless/agender people should be mushrooms. That goes for (most) animals, plants and some fungus (but not most). Well, it's super simple, males have the smaller gametes (sex cells) and females the bigger ones. So anyways, Fred, the bacteria, so why can't he be (biologically) male? What makes a male a male and female a female (biologically speaking)? So this should be awesome for Fred right? he can repopulate the town with all his clones (technically bacteria have no genders, but Fred identifies as male in this scenario, so yeah.), but you know Fred also has the power to just transfer his genes to someone else by connecting himself to this other bacteria and just sending over his genes (conjugation), now his clones don't have to be lonely and can hang out with the clones of this other bacteria. So lets say a new anti-biotic came out, great at killing all kinds bacteria, so everyone in bacteria town is dying out, but not Fred, the Bacteria who is immune to this evil substance. Well one of the ways is of course mutation, but there is also conjugation. So, what about one celled organisms like bacteria? how do they mix around their genetic information in a population if they are incapable of sexual reproduction.
While we're on subject of asexual reproduction, as you should know the negative part of asexual reproduction is that genes just don't really get mixed around a lot, which can lead to a very not genetically diverse population which becomes very susceptible to dying out for a number of reasons.
