Characteristics passed onto offspring through genes, fossil evidence, antibiotic resistence
Evidence of passed on genetics
Fossil evidence
Antibiotic resitence
Remains of organisms from millions of years ago, found in rocks
Parts of animals didn't decay as conditions for adequate decaying were absent. As organisms decayed, they were replaced by minerals. Footprints/ burrows/ rootlet trances
Had soft bodies, meaning they left little traces, any traces left have been destroyed by geographical activity.
How much or how little organisms have changed as life developed on Earth.
No remaining individuals of the species alive
new predators/ new competitors/ new diseases/ natural disasters/ loss of habitat
Reproduce at fast rate
Bacteria not killed by antibiotics
People are not immune and there is no effective treatment
Antibiotics should not be prescribed for viral infections or non bacterial infactions. patients should complete their whole course
Development of antibiotics is slow and expensive

Genus and species
Evidence of internal structures are more developed due to improvemements to microscopes and understanding of biochemical processes
