Pervasive duplication of tumor suppressors in Afrotherians during the evolution of large bodies and reduced cancer risk

open access: yeseLife, 2021
The risk of developing cancer is correlated with body size and lifespan within species. Between species, however, there is no correlation between cancer and either body size or lifespan, indicating that large, long-lived species have evolved enhanced ...

Attempted DNA extraction from a Rancho La Brea Columbian mammoth (Mammuthus columbi): prospects for ancient DNA from asphalt deposits. [PDF]

open access: yes, 2014
Fossil-bearing asphalt deposits are an understudied and potentially significant source of ancient DNA. Previous attempts to extract DNA from skeletons preserved at the Rancho La Brea tar pits in Los Angeles, California, have proven unsuccessful, but it ...

Proboscidean mitogenomics: chronology and mode of elephant evolution using mastodon as outgroup.

open access: yesPLoS Biology, 2007
We have sequenced the complete mitochondrial genome of the extinct American mastodon (Mammut americanum) from an Alaskan fossil that is between 50,000 and 130,000 y old, extending the age range of genomic analyses by almost a complete glacial cycle.

American mastodon mitochondrial genomes suggest multiple dispersal events in response to Pleistocene climate oscillations

open access: yesNature Communications, 2020
Pleistocene population dynamics can inform the consequences of current climate change. This phylogeography of 35 complete American mastodon mitochondrial genomes suggests distinct lineages in this species repeatedly expanded northwards and then went ...
