The paper introduces a new fossilized birth-death model (FBDT) that handles fossil datasets with only terminal fossils, showing it accurately estimates diversification parameters without bias.

The paper examines statistical and structural biases in birth-death models for estimating speciation and extinction rates from phylogenetic trees and provides corrections to improve accuracy.

This study uses simulations to show that plant longevity and overlapping generations explain phylogenetic patterns, with somatic mutations potentially exacerbating these effects.

The paper introduces 'tip fog' to describe variance between true species means and recorded data in comparative biology, showing its impact on model accuracy and parameter estimates.

The paper shows that apparent increases in evolutionary rates over short time scales are statistical artifacts caused by time-independent errors in data.

The paper examines the DEC model's underestimation of local extinction by modifying it to prohibit transitions into the null range, showing improved model fit and adequacy.
