In order for the pair of wings and the pair of halteres (as well as all other parts of the fly) to develop properly, the fly's suite of Hox genes must be expressed in a precise way and at precise ...

Hox genes and their relatives are involved in several developmental processes in diverse animals, but when did they first arise? The genome sequence of the sponge Amphimedon queenslandica shows ...

“[This was] striking, because we know that the Hox cluster is very conservative in terms of gene order,” said Elise Parey, an evolutionary biologist at University College London and a study coauthor.

However, later in the cascades of nearly all insects and vertebrates, the Hox genes play a role in identifying each segment and defining what part of the body each segment will become (Figure 5).

The development of body plans in all animals is controlled by a remarkably small number of genes -- and those genes are virtually identical in all animals. Clues came from instances in which the ...

Research on Hox genes, responsible for finger formation, could clarify these evolutionary mechanisms.

A series of rodent experiments showed that even with abundant food and water, personal space is essential to prevent societal collapse, but Universe 25's relevance to humans remains disputed.
