i went to this museum last summer and it was all about evolution...
here was the sequence of what i saw!
the sun + oxygen = earth!
--this was the start--
in the creation of earth and all living there were five major extinctions…then a sixth.
round one: this is where water came into play and was found.
round two:
Continents drifted together, forests and desserts were formed
the egg!
reptiles
during this extinction plant fossils have been determined to help know which season it is.
round three:
Mmesozoic era—183 million year span
periods--triassic, jurassic, cretaceous
coming alive: mammels, flowers, dinosaurs (started as tetrapods)
one out of five dinosaurs survived
round four:
continents shifted again!
50% of marine animals were extinct
95% of land plants were extinct…mainly in the northern regions
round five:
there is now over 50% of life on earth…humans!
no more dinosaurs
period: cenozoic
now!!!
three ways to be born:
plantals
marsupials
monotrenes
mammels:
rodents, hoofed mammels, carnivorans, primates
tropical plants/life:
birds
fish
Sea and water life
lucy:
3.2 million years ago
from eastern africa
one of the first hominids
-they had larger brains, flatter faces, smaller teeth, bigger trunk and smaller limbs
homosapians
-evolved around 195,000 million years ago
--according to the field museum of chicago dna supports evolution--
ice age:
1.8 million years ago today
life looked like it does today
this is when the land between north america and south america merged
types of animals: horses, dogs, bears, elephants, panthers, deer, mice, bison, gofers, beavers, etc.
tar traps began—oil was starting to kill animals.
round six:
today
began around 10,000 years ago
humans are the cause of this mass extinction—not climate change, and no, not merging continents…but, human activity
within the past year 30,000 species have gone extinct
in about one day on average 85 species go extinct
--i think this exhibit was telling us that we all fail.--
