How does fossils record help scientists observe changes in organism over time ?
As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.
What is the minimum age of a fossil?A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch.
Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).
Thus, the fossil record can be used to show that organisms changed to meet new conditions.

Jake set up an experiment. He set two aquariums with five fish of the same type and size. Aquarium one was very small, only one cubic foot. Aquarium 2 was very large at 10 cubic feet. Each day the fish were fed the same amount of food and vitamins, at the end of 5 months Jake measured the fish by length. His results are shown in the bar graph above. What might be the question Jake is asking in his experiment?
A. What fish food cost the most?
B. What fish food makes fish grow faster?
C. Does aquarium size affect growth rate of fish?
D. What type of fish food do fish like the best?
Once identified the controlled, the independent, and the dependent variables, we can say the question is C. Does aquarium size affect the growth rate of fish?
What is the independent variable?
Refers to all the variables in an experiment that provoke a response in another variable.
An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it.
It changes to analyze its effects on the dependent variable.
What is the dependent variable?Refers to the variable whose response depends on any change in the independent variable. Depending on how the independent variable is modified, the dependent variable changes.
What is the controlled variable?During an experiment, the controlled variables are kept constant. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In the exposed example,
the independent variable ⇒ Aquarium size ⇒ 1 cubic foot and 10 cubic feetthe controlled variable ⇒ food and vitaminsthe dependent variable ⇒ fishes growth.The question that Jake is asking in his experiment is Does aquarium size affect growth rate of fish? Option C.
Since he only needs to know how the size of the aquarium affects the animal's growth, he needs to keep constant other influencing variables such as food and vitamins. Otherwise, these other variables might also influence the results.
