lesson 1 early study of evolution
what are species
it is a group of simular organisms that can mat with each other and produce offpsring.
what is competition
it is the struggle among living things get the necessary amount of food, water, and shelter
what is fitness
it describes how well it can survive and reproduce in its enviornment.
What are fossil records
They are the patterns in the fossil record are like data that scientists can analyze and interpret
what are proteins
they are complicated molecules that carry out important cellular functions.
what type of fossil is on page 419
it is a armadilo fossil
on page 425 what happennds when the oxygen levels drop to low in the water
it is called Fish kill is wips out most of the local population
on page 436 what did Darwin oversimplify
he oversimplifyed evolution because he did not know about mutations.
On page 445, what are the two types of fossils
on pages 458-459 what is the picture of
it is a family tree of animals
on page 422 what is Darwins hypotheis
his hypotheis was that species change over many generations and become better adapted to new conditions
on page 426 what type of animal does darwin selctivly breed
he breed pigens with large faned shped tails
what are two ways mutations are created.
the first was is a dividing cell can make an error while copying its DNA. Secondly mutations also occur when an organism is exposed to enviornmental factors such as radiation or certain chemicals that damage the cell's.
How are fossils formed
A fossil is the impression that an organism leaves in rock.
what did darwin and scientist use to study evolution
they used their eyes, hand tools, and simple microscopes
on page 419 how long is darwins journey around the wolrld
five year trip arond the world
on page 430 what two things did darwin not understande about natural selection
The two things he didn't understand were one he didn't understand were variations come from and he didn't understand how traits were passed down from parent to offspring.
on page 439 has femals choosing males with bright feathers to have better fitness to father thier offspring.
and it is a duck
On page 449, what are the pictures on the page used for
They are used for swimming, flying, and walking
what species is a dog closer to than coyotes
they are closer to wolves
what is the name of the navy ship darwin is on
its called the HMS Beagal
on page 427 what are the three proceses of natural selection darwin identified
They are overprotection, varitaion, and competition
How many species with close interactions can affect each other's evolution?
Two or more
On page 445, what type of skull is on the page
It is a Smilodon, a cat skull
on page 463 what is it called when two organisms of different species that have closer relationship that involes living together.
it is called symbiosis
