In this little game i'm gonna evaluate your level in this part Biology! Feel ready?
Absolutely
No, not at all
You can call me Queen/King because I run this
No, next question
There are three evolutionary theories. Wich one is the correct?
Lamarckism, Creationism , Darwinism
Lamarckism, Darwinism, Catastrophism
Darwinism, Neo-darwinism, Lamarckism
Neo-darwinism, Darwinism, Creationism
Lamarck based his theory on two fundamental ideas. Write them.
(a)
According to the theory proposed by Darwin, humans and other living organisms, such as the whale, are to some degree related. This is because all organisms:
have been through processes of natural selection.
have a common ancestor.
have the capacity of heredity.
do not develop.
1- These organs appear when different ancestral species colonize similar habitats, acquire similar adaptations. This phenomenon leads to a convergent evolution.
2- These organs are formed from a phenomenon called divergent evolution, since there is a divergence of organisms from a common ancestral group that colonized different habitats and, therefore, underwent distinct selective pressures.
Choose the right one.
1 is homologous organs and 2 is analogous organs
1 is analogous organs and 2 is vestigial organs
1 is analogous organs and 2 is homologous organs
The Lamarckist theory of evolution is based on:
inheritance of acquired characteristics.
occurrence of spontaneous mutations.
inheritance of natural selection
inheritance of qualifying characters.
Giraffes extending their necks far enough, to be able to reach the leaves of the taller ones. The previous sentence, is an example of the postulate by:
Cuvier, you are responsible for changing the organisms to be able to adapt the environment.
Buffon, you are responsible for changing organisms to be able to adapt to the environment.
Lamarck, you are responsible for changing the organisms from organisms to be able to adapt the environment.
Darwin, you are responsible for changing the organisms of organisms to be able to adapt the environment.
In the previous question the most apt giraffe was the one that was able to survive. What is this process called?
(a)
Among the following ideas, which ones were later incorporated into the theory?
natural selection and common ancestry.
DNA e RNA
translation and transcription
genetic mutation and recombination
About the traditional view of how the giraffe develops a long neck, it is correct to say that:
In the traditional Darwin-based view, the giraffe acquires its long neck by the law of use and disuse. Giraffes that stretch their necks generate offspring that are already born with longer necks, and cumulatively, through generations, the neck, on average, increases in size.
In the traditional Darwin-based view, the giraffe acquires the long neck through the differential survival of giraffes. Those with long necks are able to feed on leaves inaccessible to others, and therefore leave more offspring.
In the traditional Darwin-based view, the giraffe acquires the long neck with the differential survival of giraffes. Giraffes that stretch their necks generate offspring that are already born with longer necks, and cumulatively, through generations, the neck, on average, increases in size.
"From eating vegetables so much, the intestines of herbivores gradually got longer."
Which of these theories does this sentence agree with?
Darwinism
Creationism
Lamarckism
Neodarwinism
*EXTRA*
Fixism
Through the ages there have been various ways to explain species variability. If we accept Fixism, we should wait:
simpler fossils in older rocks
simpler fossils in more recent rocks
more complex fossils in older rocks
more complex fossils in more recent rocks
the same types of fossils in older and more recent rocks
Geneticists were able to extract DNA from parts of bone that were not fossilized from a Neanderthal man who died more than 30,000 years ago. By comparing this DNA with a modern man, they concluded that we are not descendants of the Neanderthal but that he is a close relative, i.e. we have a common ancestor. This is a kind of proof that fits the arguments...

When we talk about evolution, we refer to the changes that organisms undergo through time. Several researchers had evolutionary ideas; others, however, believed that organisms were immutable. Choose all the names that refer to evolutionists:
Lamarck
Wallace
Aristotle
Darwin
How did you do?
I told you that I run this
It could have gone better
excellent
just- don't talk to me
eheheh thought it was over? Just one more
"Selection does not produce new traits." The rebuttal to:
Acquired Characteristics (Lamarck)
Mutation Theory (De Vries)
Natural Selection (Darwin)
Mutation-Selection (Neo-Darwinism)
