Interspecific Competition: When individuals of different species compete for the same resources or habitats. Thylacine: The so-called Tasmanian Tiger, it is one of the largest predatory marsupials; the last known individual was captured in 1933. Invasive Species: Any kind of organism that gets introduced to a new environment and causes harm. Holocene Extinction: The so-called sixth mass extinction, mostly involving larger animals, that started at the end of the last Ice Age, mostly due to human activity. Extinction rates during this time are 100-1000 times higher than usual. Anagenesis: The gradual evolution of a species over time. _________________________________________ Subscribe to MinuteEarth on YouTube: Support us on Patreon: And visit our website: Say hello on Facebook: And Twitter: And download our videos on itunes: ___________________________________________ Credits: Script Writer: David Goldenberg Video Illustrators: Sarah Berman and Jasper Palfree Video Director: Kate Yoshida and David Goldenberg Video Narrator: Kate Yoshida and Jasper Palfree With Contributions From: Henry Reich, Alex Reich, Ever Salazar, Peter Reich, Julián Gómez, Arcadi Garcia Rius Music by: Nathaniel Schroeder: Audio Effect: Scratch Speed by Freesound.org user Racoonanimator ___________________________________________ References: Cahill, A., Aiello-Lammens, M., M.
