Arace car driver loses his leg in an accident. apply lamarck's and darwin's theories of evolution to predict whether this disability will be carried forward by his children. in both lamarck's and darwin's theories of evolution, the physical disability will be carried forward to the children. in lamarck's theory, physical injuries will be carried forward to the children. in darwin's theory, all children will be normal since the disability is not hereditary. in lamarck's theory, all the racer's children will be normal since the disability is not hereditary, and in darwin's theory, physical injuries will be carried forward to the children.

Astudy by solloch and et. al., in 2017, gives the map above which shows the frequency of alleles with a ccr5-delta32 mutations over 87 different countries. this mutation deletes the presence of a co-receptor (ccr5) on the outside of human t-cells (lymphocytes). some viruses, such as the one responsible for the black death and human immunodeficiency virus (hiv), require this receptor for attachment to host cells during the infection process. the black death was an epidemic that passed over northern europe during the 14th century killing nearly 60% of europeans. according to this information, which explanation best explains why northern europeans show a greater immunity for hiv than some other parts of the world?
