Notes on film 10-2-12




~Iguanas in Galapagos: Marine iguana has never existed on mainland or anywhere else
~ The male sea lion  is in charge of island which makes it dangerous to be around them if u show to be competion or danger.
~the sea lions are originally from California .
~Only thing sea lions really have to look out for is sharks
~Albatrats only go to island to mate then they leave and return same time next year
~Turtles like albratats come back to island to mate from thousands of miles .
~Bobbie birds: the mother doesn't have enough to take care of both birdies so the more stronger one pushes the weaker away which basically comes down to survival of the fittest which ever one if stronger will be able to live and the overs will not.survival is grat inheritance
~Whales: been evolving for 60 million years.
~Flightless bird larger feet to paddle faster and a larger body to have more energy.
Evolution large process with millions of small steps
~FrIgit birds, females attracted to red and so they choose males that have the biggest red pouches
~Selection builds structure and pushes evolution forward.
~Competition  and variation
~South american iguana settles on Galapagos islands faced hardship and eventually it adapted which was passed down to the next generation which caused the, to survive and reproduce the best suited were able to reproduce so now marine iguanas out number the land iguanas
