As to their relationship with God, Job 39-41 makes it clear that
God is interested in animals humans don't have much to do with. (Cf.
also Sirach 18:13 - "The compassion of human beings is for their
neighbor, but the love of the Lord is for every living thing.)
But more deeply - because of our evolutionary relationship with
other species, there is a sense in which God, in the Incarnation, took
on not human nature in isolation but that of other living things. Thus
the reconciliation of "all things" (Col.1:20, Rom.8:18-25) can take
place through the Incarnation - something which, BTW, doesn't work
without evolution. More details are in my _Journal ASA_ article of 1986
(Vol.38, p.19) & book _The Trademark of God_.
