No, they cannot directly affect a change to genes. If there is a mutation in the genes (a change) and this is seen as beneficial to the individual in an environment and allows them to reproduce then it will be possibly passed on. Those with a beneficial gene for a change in environment will continue to produce offspring an survive and so the frequency of the allele (the gene) will increase and so the trait becomes more common

Considering the drifting of continents, how do you explain the abundance of marsupials and the absence of native placental mamma
garri49 [273]

Answer:

this phenomenon is a natural consequence of evolutionary processes and continental drift  

Explanation:

Marsupials are mammals in which newborn offspring are carried in a pouch of the female (mother) body. On the other hand, placentals are mammals that complete embryo development in the mother's body, in the placenta. All the extant marsupials are endemic to Australia and the Americas. It has been shown that marsupials diverged (evolved) in South America, Australia and Antarctica when these landmasses were joined. In Australia, marsupials evolved to fit an ecological niche, which can be attributed to geographic isolation due to continental drift, while placental mammals are relatively recent and more scarce (mainly bats and rodents) within this region.
