In the case of the three exemplary organisms here, they all share a common class (Malacostraca). After that, they branch off into three different orders within Class Malacostraca.  
Organisms that share more specific taxonomic levels, such as Order or Family, are more closely related that two organisms that only share a common Kingdom or Class.]]> 2017-06-01 14:23:59 UTC https://padlet.com/km034/vj72hu5q7jpt/wish/174821798 Peacock Mantis Shrimp km034 https://padlet.com/km034/vj72hu5q7jpt/wish/174980405 Odontodactylus scyllarus

However, some insects use wings instead of their legs as their main source of transportation, while crustaceans rely on their limbs.

This shows how they begin by looking similar, but then become more different as they age, showing their evolutionary relatedness in their early stages.

The molting process is controlled by a specific gene, which codes for a molting hormone. This hormone is found in many crustaceans. This shows that they all are genetically related, since this gene and its respective hormone is present in most of them.

They evolved to live solely in a freshwater habitat instead of saltwater, forming two distinct branches of crabs.

Symbiosis is thought to be a major driving force in evolutionary selection (since the first eukaryotes came from big bacteria absorbing little bacteria and coexisting). The crabs carry around the anemones and use them to fend off predators, and the anemones get the crab’s messy leftovers to eat. They have evolved to rely on one another to survive.

Currents and other ocean routes may have been the reason for distribution of their drifting larvae. This gradual speciation comes from offspring being relocated to new, isolated areas.

Females must be assured that the males will not steal their burrows, so they prefer males that are smaller than them because they are less threatening. They mate year round but peak in warmer months. Most take several mates, but some individual species will mate for life.

When a female walks by, the male waves his claw. Females choose a mate based on claw size and performance. Claw size indicates burrows width, width indicated incubation temperature, so the female chooses which one will have the best temperature for her eggs. They mate every two weeks in the summer.

They reproduce between May and September, during which time 2 or 3 broods of 30-40 young are raised.

They have micro-evolved to possess a new phenotype. Larger organisms can produce more offspring, and females with a deviation from the normal phenotype (i.e., a larger eye) produce an average of one more egg per brood.

The smaller-clawed crabs will be out-competed for habitats, food, and mates by larger-clawed crabs.

The peacock mantis shrimp passes on the trait for its punching club to its offspring. Shrimp with a faster punch could kill prey easier, and therefore survive to reproduce. Over time, the punch grew quicker and quicker until it reached the lightning speeds of mantis shrimp today.
