Document Summary
Difficult to estimate what the background extinctions were before today to evaluate whats happened today. Way to do it is looking at fossil record. but its biased towards marine and hard bodied organisms. This paper looked at new ways of estimating extinction rates by looking at phylogeny. based on diversification rates. extinction rates 1000% times higher than before humans were around. How does genetic drift influence alleles and heterozygosity: How does inbreeding influence alleles and heterozygosity: reduces heterozygosity. Compared species that were in each of those categories and looked at genetic diversity. found strong correlation in critically endangered populations (declining quickly) have more diversity than endangered populations. There can be variation that can occur just from environmental conditions when environment is developing. there is certain amount of plasticity in organisms that can respond. Examples that we can use conservation genetics for.
