illustrate biological evolution better than adaptive radiation, that is, a
rapid increase in the number of species with a common ancestor,
characterized by great ecological and morphological diversity. Almost all
real-world examples of adaptive radiation come from tropical areas. The rock
lizards <i>Darevskia, </i>a genus that contains ~25 species,<i> </i>is
an exception to the rule, as their evolution occurred entirely in the temperate
zone stretching from SE Europe to Iran. High diversity in this group is
increased even further by hybridization between the different species. In
particular, when some species hybridize, their offspring are all females, and
these females are able to reproduce without any males taking part in the
process (a biological phenomenon known as parthenogenesis). Currently, there
are six such parthenogenetic “species” of <i>Darevskia</i> lizards,
and each species is believed to have appeared independently from a separate
hybridization event. Interestingly, all parthenogens are only found in a small
area near the border of Eastern Anatolia and South Caucasus.</span></p>

<p class="MsoNormal" style="text-align:justify;margin:0cm 0cm 8pt;line-height:107%;font-size:11pt;font-family:Calibri,sans-serif"><span style="color:black;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial">In our study, we are using various methods of genotyping the
hybrid parthenogenetic species and their parents. With the help of the modern
methods of genomics, we were able to establish exactly where the former have
originated, estimate the approximate times of their origin, and pinpoint
precisely which extant parental populations are their closest genetic
relatives. The important question is how the all-female populations have been
able to withstand the ever changing environment and successfully compete with
the parental species on the evolutionary time scale. We are now testing several
new hypotheses that might help to explain how the genetic diversity is
maintained in the parthenogenetic species.</span></p>

he graduated with a university degree in biology. Soon after finishing his PhD
at Schmalhausen Institute of Zoology in Kyiv, he moved on to several
postdoctoral positions in Scotland, New Zealand, California and the Czech
Republic. In late 2015 he was invited to run a teaching and research program as
a faculty member at Bülent Ecevit University in Zonguldak. Alexey’s research
interests included, in different times, the population genetics of amphibians,
theoretical population biology, and evolutionary genetics of the house mice.
Since he moved to Türkiye, he is mostly focused on exploring the genetic basis
of incredible biodiversity of Anatolian and Caucasian biota, which sometimes
include humans and even bacteria.</span></p></div></div>
