but who can say that the dwarfed condition of shells in the brackish waters of the Baltic, or dwarfed plants on Alpine summits, or the thicker fur of an animal from far northwards, would not in some cases be inherited for at least a few generations?
baina nork esan dezake Baltikoko gesaletako maskorren nanismoa, edo Alpe gailurretako landare nanoak, edo Iparralde urruneko animaliaren ilaia trinkoagoa ez direla kasu batzuetan heredatuak, zenbait belaunalditarako bederen?
