BIODIVERSITY&STABILITY Flashcards
proposed the idea that all species descend from an ancestor
Charles Darwin
what are the evidences of Evolution
Fossil Record
Comparative Anatomy
Embryology
Molecular Evidences
vital understanding relationships among creatures
Comparative Anatomy
remnants of an creature from the primitive times
Fossil Record
provides clues to its evolutionary past
Embryology
same structure, diff function
Homologous Structure
same function, diff structure
Analogous Structure
Theory of? (changes based on their environment)
Theory of need
Theory of ? (the organs that will not be used disappear and vice versa)
Theory of use and disuse
Theory of ?(changes over lifetime pass to offspring)
Theory of Acquired behavior
3 theories by Jean Baptiste De Lamarck
Theory of need
Theory of use and disuse
Theory of Acquired behavior
Theory of Charles Darwin
Theory of natural selection (the strongest survives)
the variety of life on earth and their interactions
Biodiversity
provides visual or artistic enjoyment.
Aesthetic Value
if there are benefits produced by the organism without using them
Indirect Economic Value
considered to have direct economic values if their products are sources of food, medicine, clothing, shelter, energy
Direct economic value
known as the 17 megadiverse countries
Philippines
Structural Adaptation:
disguise their appearance
Camouflage
Behavioral Adaptation:
sleep in response to cold weather
Hibernation
Structural Adaptation:
imitate and copy another species
Mimicry
Structural Adaptation:
gas harmful to invading organism
Chemical Defense
Structural Adaptation:
protect and cover the body
Body Coverings
Behavioral Adaptation:
Travel from one place to another
Migration
cannot be passed on the next generation except teaching
Learned Behavior
group of organism belonging to the same species and can interbreed
population
monitor the number of organism
Ecologist
The record of organisms that can increase or decrease each seconds
Population Change
number of births
Natality (Birth Rate)
number of deaths
Mortality (Death Rate)
influenced by diseases and parasites, competition for resources, predation, emigration
Density Dependent
total number of members of a population
population size
An anatomical feature or behavior that no longer seem to have a purpose in the current form of an organism of the given species
Vestigial Structure
number of organism in a population (population density = individuals ÷ land area)
population density
max number of people can live in a area
Carrying capacity
Ways to check the age of Fossil
Relative dating and Absolute Dating
Fossils are found in?
Sedimentary Rock
The oldest era of Fossils discovered
Pre cambrian or Palezoic
study of the distributions of organisms
Biogeography
set of genetically developed traits that make the organism better suited to its environment
Adaptation
vertebrate forelimbs are most likely to be studied in
Comparative anatomy
