Evolution's just
a theory But it's pretty clearly real
Realistically it can't become a law Because it isn't something we saw
Organisms were prokaryotes formed eukaryotes
In coexisting relationships And symbiotic friendships
Earth is 4.6 billion years old And the ocean begins to unfold
All the continents were connected And then plate tectonics wrecked it
It began with invertebrates Then marine life populates
And then stuff popped up at a surprising rate As dinosaurs and mammals and birds were made
(And dinosaurs ate the losers)
To time this all Preserved fossils were traced
Way back when life First took place
Relative age is determined by stacks Absolute age determines the years that they've
passed Also known as the half lives elapsed
Using carbon, potassium and uranium to measure the past
Charles darwin was a pretty cool cat But his discoveries nearly drove him mad
Living and fossil diversity Adaptation and fitness faced controversy
Genetic inheritance, modification and natural selection Made up an evolution connection
That fossils have similar features Like embryos and bone structures
Artificial selection makes the best even better Unless natural variation made the fitness
lesser With natural selection the environmentally
fit As species strive for perfection the hip ones
live
You have to be attractive to get the babes For your genes to pass on you need them to
mate But if your competition is not weak
Your lumpy genes must claim defeat
Genetic drift is like a random trick More pronounced in small populations
When there's a sudden change in allele frequency Causing genetic alterations
What causes speciation geographic and *** isolation
And sometimes hybridization Creates a unique genetic population
(Banana sex not to mention pollination)
Adaptive radiation is when new species form different species
And different ways all in the same place Convergent evolution is when differencees
Form superficial similarities (to get along with nature)
Gradualism and punctuated Are the theories about what evolution is paced
at Relationships with DNA is molecular unity
and different geographies cause biodiversity
And humans are just like chimpanzees Except we pollute the seas
And kill the bees
And cut down trees
