Match the type of of evidence for evolution with the correct example. analogous structures vestigial structures homologous struc
gogolik [260]

• Homologous structures: Both Ostriches have wings similar in form to those of their ancestors, but that do not allow the birds to fly.

Homologous structures are those that have structural similarities but are different in function. For example, if we look at the anatomical structure of a bird’s wing, it is very similar in structure with a human arm. However, over the course of time they have evolved to perform different functions.

• Vestigial structures: The inner ear bones of mammals have evolved from bones that form the jaws of reptiles.  

Vestigiality refers to the process in which some structure lose their function over the course of evolution in some specie but they are functionally normal in other species.  Such a structure is the inner ear bones of mammals which donot perform an important function in mammals but do perform in reptiles.

• DNA sequence data: Both Genes involved in RNA replication are conserved among bacteria and animals, suggesting a common evolutionary origin.

The sequencing of genetic data is an excellent method of finding the evolutionary histories and relatedness of different organisms. This field of sciences is called phylogenetics and the mentioned example is the result of phylogenetics.

• Analogous structures: The jointed legs of insects and vertebrates arose independently, indicating a different evolutionary origin.  

Analogous structures are those that have similar function but they look very different in structure or anatomy. This is because they have been evolved from different ancestors and perform different functions. One example of these structures is mentioned, The jointed legs of insects and vertebrates that look different bur perform same function.

Which genetic variation occures during fertilization when the egg and sperm meet?
Zina [86]
Answer: crossing over

during the process of fertilization, a sperm and egg join together to create a zygote. since a sperm had half the number of chromosomes and an egg has half the number of chromosomes, when they join together the zygote had a complete diploid set of chromosomes. the assortment of chromosomes and crossing over promotes genetic variation during the process of reproduction
