Inherited traits
What is the significance of the traits seen in offspring?
What is the basis of the origin of species according to mutation?
What is the criticism of Hugo De Vries' mutation theory?
Criticism of Hugo De Vries Mutation Theory
Lamarckian plants are hybrids of old species, and the new traits seen are due to chromosome segregation and rearrangement, not mutation.
The theory of mutation does not provide a definite direction for evolution.
If mutations are traits that appear randomly, those organisms (mutants) cannot adapt to the environment, but this is not observed.
It is not found that he described the role of nature in mutation.
Generally, traits that arise from mutation are recessive.
Who is the proponent of the theory of natural selection?
Charles Darwin
Lamarck
Hugo De Vries
Gregor Mendel
Which is an example of homologous organs?
Our hand and the front leg of a horse
Our hand and the trunk of an elephant

The canine teeth found in humans and lions
Where are fossils found?
Sedimentary rocks
Igneous rocks
Metamorphic rocks
Volcanic rocks
What is the process called when changes in the genetic structure lead to new traits appearing in offspring?
Evolution
Mutation
Transformation
Residual traits
The evidence obtained from fossils provides a strong basis for evolution.
Even if the number of offspring born is high, the population of organisms does not increase.
Change is not the only factor in the origin of new species.
Humans, monkeys, horses, and birds are believed to have evolved from the same ancestor.
