Experiments
spontaneous generation
which type of cell would have evolved first
prokaryote
fungi, animals, plants
define adaptation
characteristics of an organism that enhance their survival and reproduction in a specific environment
father of evolution, came up with the idea of natural selection
Darwin
Redi
method of gathering energy for the first cells
chemo- or photosynthetic
the time when every animal group appears in the fossil record
Cambrian Explosion
describe descent with modification
all organisms descended from a common ancestor that lived in the remote past and species have changed over time
scientist whose theory of acquired characteristics has been disproven
Lamark
what was unique about Pastuers flasks
they were a swan neck- no microorganisms could travel through the curve
the first cell-like strucutres to appear were coaceratives. What are the main components of a coacerative
lipid bubble, amino acids (other macromolecules) inside
name 1 adaptation that plants needed to survive on land
vascular tissue (xylem/phloem)
waxy cuticle to prevent water loss
pollen grains to transfer sperm without the use of water
which individuals will survive and reproduce is based on
their fitness- how well suited they are for their environment
Cuvier
what element was NOT present in Miller-Urey experiment
oxygen
heritable material (RNA)
prokaryotes reproduce ________. when they replicate their genetic material divides and produces 2 ____________ cells
asexually, identical
process in which individuals with favorable traits will survive and leave more offspring than those with less favorable traits
natural selection
scientist who said that layers of rock form slowly over time and valleys and mountains can be shaped by natural forces. but this process would take millions of years
Hutton
what are the 4 main components of the Miller Urey expeirmnetal set up
gasses , water, lightening(sparks), heat
theory that a larger prokaryote engulfed a smaller prokaryte and evolved into our eukaryotic organisms over time
endosymbiosis
what are the 2 organelles that were engulfed during endosymbiosis
chloroplast, mitochondria
natural selection can ONLY work with ______ _____
heritable traits
developed the idea of uniformitarianism- the mechanisms of change are uniform over time, the same changes that happened in the past are still occurring today
Lyell
