Unit 14 Flashcards
Malthus
predicts that the human population will grow faster than the space and food to sustain it
Lamarck
first to hypothesize the inner tents of acquired traits for change over time
Darwin
come up with idea of natural selection
homologous structure
similar atomically but used for different activities
vestigial structures
no longer in use
analogous structures
similar in use but are different atomically
embryology
vertebrates in early stages
decent with modification
species similar environmental conditions will evolve in the same directions even if they are from 2 different species
adaptive radiation
the process of a single species or small group of species evolving natural selection into many different form that live in different ways
convergent evolution
process by which unrelated organisms come to resemble one another over evolutionary time
coevolution
process by which two species evolve in response to changed in each over time
punctuated equilibrium
a pattern long stable periods with almost no visible evolution interrupted by brief periods of more rapid change
when does punctuated equilibrium usually occur
after a mass extinction when habitats are now open to newcomers
advantageous characteristics
binocular vision
well developed cerebrum
long fingers and toes
arms that can rotate around shoulder blades
what features do hominoids have
large brain
thumb for grasping
can walk up right
