Important genetic origin of our senses identified

Having a head is quite an advantage. Although this may sound banal, it had to be tested in a long evolutionary process: As animal life developed, invertebrates initially dominated the oceans. These had already developed head ...

These bats deter predators by buzzing like hornets

In Batesian mimicry, a harmless species imitates a more dangerous one in an evolutionary "ruse" that affords the mimic protection from would-be predators. Now, researchers reporting in Current Biology on May 9, 2022, have ...

New study shows spiders use webs to hear

Everyone knows that humans and most other vertebrate species hear using eardrums that turn soundwave pressure into signals for our brains. But what about smaller animals like insects and arthropods? Can they detect sounds? ...

Sequencing puts carnivore chromosomes in context

Studies comparing animal genomes generally focus on the DNA sequence itself. A new study by researchers at the University of California, Davis shows how the three-dimensional scaffolding of chromosomes is related across several ...

Developmental origins of tooth classes in vertebrates

The researchers from the HiLIFE Institute of Biotechnology, University of Helsinki compared two central bearded dragon lizards (Pogona vitticeps): a normal one and a mutant with no body scales. They identified striking differences ...

Building a human body through gastrulation

A collaboration of researchers from Japan, Spain and the U.S. offers a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, ...
