We found that individual foram growth rates were influenced by temperature at the time of growth. However, shell shape such as the angle of chamber addition was not environmentally dependent, so likely determined solely by genetics.

…but planktonic forams do! They build a new chamber every few days and store environmental data in their calcite. So, we can assess the influence of environment on growth *in the fossil record*

Developmental plasticity is when a single set of genes can produce several different phenotypes, depending on the environment the individual grows up in. For example, sea turtle sex depends on the temperature of the nest. Human body weight depends on both genetics, and nutrition during childhood

My Etsy shop is open again! Foram earrings, keychains, pins, stamps, you name it!
