Early Primates Primarily Inhabited Cold and Temperate Climates, New Study Suggests

Primates historically transitioned across diverse climates: (A) transition between the temperate (top), arid (left), tropical (bottom), and cold (right), main climates, for all primates; arrow size represents the proportion of phylogenetic branches with the respective transitions; (B) climatic transitions for early primates, who were living between 65 and 47.8 million years ago; (C) climatic transitions for species that were living between 47.8 and 23.03 million years ago; (D) climatic transitions for species that were living from 23.03 million years ago to the present.

Textbooks often portray primates as originating, evolving, and dispersing exclusively within warm tropical forests. This tends to come from fossil evidence distributed across tropical latitudes. However, new research led by University of Reading suggests first primates most likely lived in North America in a cold climate with hot summers and freezing winters. Primates historically transitioned across diverse climates: (A) transition between the temperate...

Black holes are the sources of the strongest gravitational fields that can be found today in the Universe and are ideal laboratories for testing Einstein’s theory of general relativity in the strong field regime. In his article, Professor Bambi shows that the possibility of an interstellar mission to send a small spacecraft to the nearest black hole, although very speculative and extremely challenging, is not completely unrealistic.

This Hubble image shows of the outer arms of NGC 45, a spiral galaxy some 22 million light-years away in the constellation of Cetus. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3) instrument. It is based on data obtained through seven filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Interspecific hybridization may trigger species radiation by creating allele combinations and traits. Cultivated potato and its 107 wild relatives from the Petota lineage all share the distinctive trait of underground tubers, but the underlying mechanisms for tuberization and its relationship to extensive species diversification remain unclear. Through analyses of 128 genomes, including 88 haplotype-resolved genomes, Zhang et al. revealed that Petota is of ancient hybrid origin, with all members exhibiting stable mixed genomic ancestry, derived from the Etuberosum and Tomato lineages ca. 8-9 million years ago.
