Vocab
Are preserved remains or traces of living things?
Fossils
Scientists cannot yet pinpoint when or where life first evolved.
True as the sun
The term petrified means "turn into stone"
Yeap, that´s exactly what it means :)
Each new discovery helps to fill holes in our understanding of evolution.
True
The structure of an organism´s body is called?
anatomy
is a young organism that develops from a fertilized egg?
embryo
You can´t determine climate change through fossil records.
This is false false my friend!
Was the earth formed thousands, millions or billions of years ago?
well of course billions of years ago
What is a trace fossil?
footprints, nests and animal droppings preserved in stones.
is the small, solid pieces of material that come from rocks or the remains of organisms and settle to the bottom of a body of water?
sediment
a specie that no longer exists and will never again live on Earth?
Extinct
We can learn about what a plant or animal looked like from a trace fossil.
False (body fossils)
Only hard parts of an organism typically leave fossils, this hard part include? Mention at least 3.
bones, shells, teeth, seeds and woody stems.
Rock forms in layes, with newer layers on top of older layers.
True
This is when there is a major evolutionary change?
macroevolution
Similar structire that related species have inherited from a common ancestor are know as?
homologous structures
Similarities in anatomy are clues that organisms evolved from a common ancestor.
If you answered true, then you are most certainly correct.
An impression of a fossil comes about in one of two ways.
a mold creates a hollow area in the rock that is the shape of an organism or part of an organism. Or a cast makes a solid copy of an organism´s shape.
The oldest rocks contain fossils of both complex and simple organisms.
Oh come on! its false (young rocks)
small, gradual changes in the color or size of a certain population is called?
microevolution
is the wearing away of Earth´s surface by natural process such as water and wind?
erosion
Some species in the fossil record seem to change rapidly over time, such as the elephant.
You better answer false (change gradually)
Mention 5 causes for extinction
Loss of habitats, invasive species, lack of genetic diversity, lack of food, pollution, human predation, disease, climate change and better adapted competition.
What information could scientists get out of fossil records?
documents the diversity of the life forms, many now extinct and shows how life forms existed and changed throughout Earth´s history.
Name the two types of fossils.
Body fossils and trace fossils
