Human impacts such as habitat loss, climate change and biological invasions are radically
altering biodiversity, with greater effects projected into the future. Evidence suggests human …

The endosperm, a transient seed tissue, plays a pivotal role in supporting embryo growth
and germination. This unique feature sets flowering plants apart from gymnosperms …

Speciation is driven by the evolution of reproductive isolating barriers that reduce, and
ultimately prevent, substantial gene flow between lineages. Despite its central role in …

Many biodiversity studies focus on explaining high tropical species richness, but an equally
dramatic yet understudied pattern involves the divergent richness of land, sea and …

Mammalian taxonomies are conventionally defined by morphological traits and genetics.
How species differ in terms of neural circuits and whether inter-species differences in neural …

The origins and evolution of the outstanding Neotropical biodiversity are a matter of intense
debate. A comprehensive understanding is hindered by the lack of deep-time comparative …

When lineages of hosts and microbial symbionts engage in intimate interactions over
evolutionary timescales, they can diversify in parallel (ie, co‐diversify), producing …

The scenario of Homo sapiens origin/s within Africa has become increasingly complex, with
a pan‐African perspective currently challenging the long‐established single‐origin …

Charles Darwin presented a unified process of diversification driven by the gradual
accumulation of heritable variation. The growth in DNA databases and the increase in …

Species diversification—the balance between speciation and extinction—is fundamental to
our understanding of how species richness varies in space and time and throughout the …
