In the course of evolution, animals have repeatedly shifted from sexual to asexual reproduction. The first evidence of the consequences of parthenogenesis – a type of asexual reproduction – on genome ...
Life cycles require the creation of an autonomous individual, that individual’s growth and that individual’s reproduction In ...
Studying a species of beetle mite, an international research team has demonstrated for the first time that animals can survive over very long periods of time (possibly millions of years) entirely ...
