On living beings: biological and philosophical aspects.
This is an interdisciplinary work (biology-philosophy) product of reflection on the
challenges today presented by a biological vision of the world regarding questions, concepts and
notions of cosmology (Philosophy of Nature). Based on and in dialogue with the current state of
biological research, this work deals with certain cosmological problems such as that between the
living and the inert, the traditional division between the soul or the vital vegetative principle, sensitive
or intellective; the problem of individuation and the concept of species, among others; the solution
found within classical philosophy in this paper takes into account the latest discoveries findings of
modern biology.post-print165 K

The Origin of Man in the Light of Three Fields of Knowledge: Science, Philosophy and Theology.
The reception and development of Darwin’s
ideas have displaced mankind from the central
place in the Cosmos, becoming no more than
another evolved animal. This work offers a criticalscientific
critique of the dominant ideas in the field
of scientific research and debate into the origins of
Man. By means of an interdisciplinary analysis
(science, philosophy, and theology) of the scientifically
proven facts, it is concluded that specimens
classified in the genus Homo constitute a single
species whose morphological evolution (hominization)
is posterior to its humanization.post-print391 K

A new species of Entomobrya from Iraq (Collembola, Entomobryidae)
The systematic study of Entomobrya specimens from different museums in the Palaearctic region
and material obtained from other collections allowed some new species of the genus to be revealed.
Entomobrya iraqensis n. sp. is described from Mosul, Iraq. For the identification and description of the
species, the set of characters proposed by Jordana and Baquero (2005) was used
A proposal of characters for taxonomic identification of Entomobrya species (Collembola, Entomobryomorpha), with description of a new species
The species of the genus Entomobrya have bean traditionally identified using colouration. Only
some authors have considered a small number of morphological characters, in badly mounted or old
specimens, as well as chaetotaxical characters (but not used for species identification). The study of a
large series of slides from extensive collections of Entomobrya species with observation of the complete
chaetotaxy has demonstrated that specimens with the same colour pattern can have a very different
chaetotaxy, which is related with the geographical origin. On the other hand, specimens with similar
chaetotaxy but from distant geographical areas maintain the same colour pattern. The present paper
proposes a set of both morphological and chaetotaxical characters as a useful tool for the species
identification in the genus Entomobrya in connection with the observation of colour pattern. For the
selection of this set of characters more than 500 slides from the top-ranking European museums have
been studied. Two species of the genus with similar colour pattern but with a different chaetotaxy are
used as models for the methodology: E. nivalis (Linnaeus, 1758) and a new species from León (Spain)."By kind permission of Senckenberg Museum für Naturkunde Görlitz; copyright by Senckenberg Görlitz. See also: www.soil-organisms.org
A new species of Entomobrya (Collembola, Entomobryidae) from La Caldera de Taburiente National Park (La Palma Island, Canary Islands) and its associated collembolan fauna
Entomobrya palmensis n. sp. is described from the Canary Islands (Macaronesian Region). The new
species shares the colour pattern with E. multifasciata (Tullberg, 1871), but clearly differs in chaetotaxy.
A list of species and locations of the collembolan fauna of the area is given
