Convergent Evolution Has Fooled Us: Most of Our Evolutionary Trees Might Be Wrong

Elephant shrews are more closely related to elephants than shrews, according to molecular evolutionary trees. An evolutionary tree, or phylogenetic tree, is a branching diagram showing the evolutionary relationships between various biological species based on similarities and differences in their characteristics. Historically, this has been done using their physical characteristics – the similarities and differences …

Study of over 800 planet-forming disks reveals startling planetary evolution

Is our solar system comparable to other solar systems? What are the other systems like? We know from studies of exoplanets that many other systems have hot Jupiters, massive gas giants that orbit extremely close to their stars. Is this normal, and our solar system is the outlier? One way to address these questions is …
