Important Questions on Heredity and Evolution
”Inherited traits are capable of directing evolution”. Justify the statement and support your answer by giving two reasons.
With the help of suitable examples, explain why certain traits cannot be passed on to the next generation. What are such traits called? Name two homologous structures in vertebrates. Why are they so called? How do such organs help in understanding an evolutionary relationship?
State any two factors that could lead to the rise of a new species. How do analogous organs provide evidence in favour of evolution? Why traits such as intelligence and knowledge cannot be passed on to the next generation? How can we say that birds are closely related to reptiles and have evolved from them? Place the following in correct sequence: Natural selection, migration, new species and gene flow.
