(2020)\n), three growth-rate curves\nrepresenting the ontogenetic growth trajectories of animals and\nplants against time, and the axially symmetrical and integral\nforms of all these functions (Shi et al. (2017)\n; Shi et al. (2021)\n). The optimization method proposed by\nNelder and Mead (1965) was used to\nestimate model parameters. 'biogeom' includes several real data\nsets of the boundary coordinates of natural shapes, including\navian eggs, fruit, lanceolate and ovate leaves, tree rings,\nseeds, and sea stars,and can be potentially applied to other\nnatural shapes. 'biogeom' can quantify the conspecific or\ninterspecific similarity of natural outlines, and provides\ninformation with important ecological and evolutionary\nimplications for the growth and form of living organisms.\nPlease see Shi et al.
