Alba Landra uncovers the ancient ancestry that underlies modern human evolution. MODERN HUMANS have managed to reach every corner of the globe and with current population sizes rising rapidly, we could stake a claim to being the most ‘successful’ hominid species yet. However, how much has our recent ancestry impacted our evolution, and have our previous interbreeding events helped, or even hindered, our success as a species? About 100,000 years ago,

Throughout history, being able to sustain a growing population has been at the forefront of the minds of philosophers, politicians and scientists alike. We have always managed to find a way to feed the population,

These ethical issues are to do with when the onset of human personhood is. The reprogramming of somatic cells to produce induced pluripotent stem cells avoids the ethical problems specific to embryonic stem cell research.
