Anthropolgy has certainly moved on since 1877!  One of the best books seeking to vindicate the idea of social evolution (which for a while some anthropologists denied) from a position sympathetic to Lewis Henry Morgan is The Evolution of Culture by Leslie A White that first came out in 1959.White was an active member of the DeLeonist Socialist Labor Party of America from 1929 to 1946 writing for the Weekly People, etc and remained a member afterwards till 1959 (he died in 1975). For more info on him and his anthropological theories see here and here.
