 Forensic Entomology 

Forensic  entomology is the Scientific study of the invasion  of the succession pattern of arthropods with their developmental stages of different species different in species  found on the decomposed cadavers during the legal investigation. 
                   It is the application and study of insects , arachnids , centipedes ,  millipedes and crustacean to criminal or legal cases.It also helps to detect drugs and poisons, determine the location of an incident and find the presence and time of the infliction of wounds.

               Forensic entomology has 3 sub fields :-

  1. Urban forensic entomology:-  
  • urban forensic entomology typically concerns pests infestation in building , gardens or that maybe basis of litigation between private parties and service providers such as landlord or extreminators.
  • It helps to determine chain of custody , when all the possible infestation are examined in order to determine who is at fault.
  1. Stored - product forensic entomology :-
  • Stored product forensic entomology is often used in litigation over insects infestation or contamination of commercially distributed foods
  1. Medico- legal forensic entomology :-
  • Medico legal forensic entomology covers evidence gathered through anthropod studies at the schemes murder , suicide , rape , physical abuse and contraband trafficking.
Application of forensic entomology :-
  • Scorpionfiles ( insect ):- presence of scorpionfly indicates that a body must be fresh.
  • Blowflies ( insect) :- ability to smell death from ten miles (16 km)
  • Flesh flies (insect) :-Breed in carrion, dung, garbage , or decaying wounds of mammals 
  • Humpback flies (insect):- larvae feed on decaying bodies 
  • Rove beetles  :- found on the corpse when it more decomposed
  • Hipster beetles:- carrion feeding species 
  • Mites:- feed on corpses in early stages of decomposition 
  • Moths :- feed on mammalian hair during their larval stages and may forage on any hair that remains on a body
  • Wasps , ants and bees :-feed on body , some are also predatory, and eat the insects feeding on the body

Chapter -2 Biological classification

  Biological classification is the scientific procedure of arranging organisms into groups and subgroups on the basis of their similarities and dissimilarities and placing the group in a hierarchy of categories. Importance of classification :-  It is not possible to study every organism. Study of one or two organism of a group gives sufficient information about the essential features of the group. It helps in identification of new organism. Classification helps in knowing the relationship amongst different groups of organisms. The organism of past cannot be studied without a proper system of classification. Classification :-  (i)Artificial system of classification (ii)Natural system of classification (iii)Phylogenetic system of classification (i)Artificial system of classification- Only one or two morphological characters for grouping of organism is used. Flowering and non-flowering plants, enaima and anaima. Aristotle classification. (ii)Natural system of classification- Takes into

Human Eye

 Human Eye The human eye is a remarkable and complex organ responsible for vision, allowing us to perceive the world around us. It collects and processes light, converting it into electrical signals that are interpreted by the brain as visual images. Here's a detailed description of the eye's anatomy and its main components: Anatomy of the Eye: External Structures: 1. Eyebrows: The eyebrows are located above the eyes and serve to prevent sweat and other particles from falling into the eyes. They also play a role in nonverbal communication and facial expressions. 2. Eyelashes: Eyelashes are situated at the edges of the eyelids and help protect the eyes by sensing and reducing the amount of light, dust, and debris that enters. 3. Eyelids (Palpebrae): The upper and lower eyelids cover and protect the front of the eye. They also help distribute tears over the surface of the eye, keeping it moist and clean. 4. Conjunctiva: A thin, transparent membrane that covers the front

Origin of Bilateria

 Origin of Bilateria                                        First meta zones are very likely to radial animals Believed that bilateral symmetry evolved in radical ancestor when it is started creeping There are several theories given by many scientists for the Bilateria symmetrical animals are as follows:- 1.Ctenophore polyclad Theroy  :-  Ctenophores provided a a bridge or intermediate forms between                 radiate coelonterate and ancestors  and bilateral polyclad flat warms. Based on resemblance:- Oval flat and shaped with dorsal ventral differentiation Creeping on entire ventral surface Presence of two dorsal tentacles Centrally located ventral mouth Radiating, anastomosing nervous system Swimming larval stages of polycalds have eight ciliated lobes and comparable  to 8 comb rows of ctenophore  Limitations:- Cleavage is biradical in ctenophore but spiral in polyclad  Acoel flatworms are now regarded to be a most primitive 2.Planuloid-Acoeloid Theroy:-   Ludwig Von Graft form
