early study of evolution
early study of evolution
What is a fossil?
The preserved remains or traces of an organism that lived in the past.
What is natural selection?
a mechanism of evolution.
What did humans evolve from?
Monkeys (not really, because we don't have proof, and God made us anyway.)
what happens when something goes extinct?
It dies and and then there are no more of it.
What proof do people have that evolution is real?
They don't have full proof. They are just giving out theories
Who was Darwin?
A man who observed and studied the natural world.
Why do people believe in evolution?
We have so-called "evidence" that living things from the past evolved into what we have today.
How many chromosomes to humans have?
46.
How do fossils form?
they get burried and then over time it gets imprinted into the dirt or preserved.
A molecule found inside the cells of all living things that provides the ultimate evidence of a shared genetic code.
What is DNA?
What did Mary Anning's Family make money from?
Finding fossils.
What is the importance of natural selection?
Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success.
How many chromosomes are given to the child from the mom?
23
how many types of fossils are there?
2.
The fact that all life on Earth uses the exact same genetic code is considered absolute proof of this evolutionary concept.
What is a common ancestor?
What is Evolution?
The theory that living things from the past evolved into what we have today.
what is the cell cycle?
the series of events in which a cell grows, prepares for division, and devides to form two daughter cells.
How many chromosomes are given to the child from the dad?
23.
What are the different types of fossils?
body fosssil, and trace fossil.
The process or result of changing to better suit new environments or conditions.
what is adaptation?
Who was the first person to develope scientific names for organisms
Carl Linnaeus
who had the idea that inheritance and probability can be applied to all living things?
Gregor Mendal.
How many genes are found in on the 46 chromosomes?
20,000-25,000
what is the difference between a body fossil and a trace fossil?
body: preserve the shape and structure of an organism.
trace: Shows us what and animal did
(ex: foot prints)
The study of where organisms live on the planet and how they got there based on geography.
what is biogeography.
