naming and classification

Question 1

what are the 8 stages of classification

Answer 1

Domain
Kingdom
Phylem
Class
Order
Family
Genus
Species

Question 2

what is phylogenetics

Answer 2

study of evolutionary relationships through observable characteristics

Question 3

what is cladistic analysis

Answer 3

a means to classify animals to match their evolutionary history

Question 4

what are the 5 main modern technologies

Answer 4

• photographic evidence
• dna analysis
• drones
• gps tracking
• microscopy

Question 5

how is photographic evidence important in classification of animals

Answer 5

• images allow scientists to examine physical characteristics without needing live specimen present
• helps identify elusive or endangered species and monitor behavioural traits

Question 6

what are advantages of using photographic evidence

Answer 6

allows for classification without disturbing the animal
lasting visual evidence
observation in natural environment
useful in remote locations
supports education
easy to store

Question 7

what are disadvantage of using photographic evidence

Answer 7

internal anatomy and genetics cant be observed
poor image quality can lead to incorrect classification
difficulty to access size / weight / some behaviour
requires access to expensive equipment

Question 8

what is dna analysis

Answer 8

classification based on genetic material, research of evolutionary relationships.
dna barcoding involves analysing short setions of dna to match and identify induviduals

Question 9

what is dna barcoding

Answer 9

• looking at a small section of dna to match individuals to species

Question 10

advantages of using dna analysis

Answer 10

• high accuracy
• identify all life stages
• supports discovery of new species ​
• non-visual evidence​
• reveals evolutionary relationships ​

Question 11

disadvantages of using dna analysis

Answer 11

• expensive
• specialist skills
• contamination risk
• doesnt show external traits
• ethical considerations

Question 12

what is gps tracking

Answer 12

• used to monitor movement and migration
• tracing devices attached to animals, these send the location to satellites
• helps scientists understand the lifestyle of specific species

Question 13

advantages of using gps tracking

Answer 13

• non invasive
• real time data
  -identification
• tracing migration
• supports conservation

Question 14

disadvantages of using gps tracking

Answer 14

• expensive
• only for larger animals
• battery and signal reliant
• requires animal capture
• doesnt provide genetic or physical dats

Question 15

what is microscopy

Answer 15

• way of observing small structures for research and identification
• helps in distinguishing between species

Question 16

advantages of using microscopy

Answer 16

detailed
needed for microscopic species
cell and tissue analysis
good in combination with other methods

Question 17

advantages of using microscopy

Answer 17

• specialist equip
• expert knowledge needed
• limited to small features
• time consuming
• often needs to be combined with other data
