Can anyone me in biology evolution ?

1,4,5 is correct

Explanation:

To look at which species is more closely related to another, look at the number of intermediate ancestors between each species. The lesser the number of ancestor intermediates, the closer the relatedness the species is to the common ancestor.

As long as the species is in the phylogenetic tree, the species may share a common feature with the common ancestor

it would lead to upper respiratory infections and pneumonia.
